If its a forever change, I'd get a new chain while your at it. That way you can cross chain all you want w/o worrying about the bad stuff that can happen. But check to see if the rear D can handle a cassette that large. Mostly has to do w/ cage length. Standard roadie forever has been short cages and up to 28t. The new gen stuff I don't know about w/o having to get a new rear D such names like SRAM Wifli that will handle a 32t.

Yes you can do it at home if you have the tool to loosen the retaining ring and a chain whip. You're running a 10 speed cassette, right? Your freehub might have a spacer on it if it has the capacity for an 11 speed cassette. If so you would just leave that spacer on it. The other spacers between the cogs you keep the old ones where they are on the old cassette and put the new ones from the new cassette on in the same order as it comes out of the box.
You may need to screw in the derailleur's b screw a little due to the slighter larger 30 cog, need to keep the top pulley from contacting the cog. You also might have to give your derailleur's barrel adjuster a bit of a turn, likely no more than 1/4 turn in one direction or the other. Maybe a very slight adjustment on the limit screws, but probably not needed. If you've adjusted one before it's not a problem, if you never have it is a bit intimidating at first but not difficult. Basically just want to get the derailleur pulleys to line up directly under each cog so it runs quiet and shifts well (barrel adjuster) and make sure that the derailleur does not go too far in or out to cause the chain to overshoot the top or bottom cogs (limit screws).
Also need to make sure your chain is long enough to allow for the larger cog, it is only 2 more teeth and the chain goes round only 1/2 the cog so it probably is long enough already. Mine was when I made the change. Which was nice because I had a new chain with less than 300 miles on it when I got my new wheels and cassette.
Are you going to do one of the BCI rides on Saturday? I'll be there and we could be sure you've got it dialed in before heading up GMR.

I have this bike Specialized Bicycle Components unfortunately I'm pretty useless when it comes to mechanical things as an IT guy, but I'm slowly learning a few tricks. How would I know if the read derailleur can handle the cassette or not. Do I just call Shimano directly and give them my part numbers?

current chain life means nothing. You need a longer chain if you want larger gears in the back. Not doing so will stretch the spring in the rear D past the limits and bad things may happen. Broken chain if lucky, broken rear D hanger would be 95% chance. The rear d hanger is made from soft cast alum w/ 2 M3 screws holding it to the frame (designed to break). This type of failure can send the rear D into the spokes, causing full wheel lock up or worse into the wheel + chain stay breaking the carbon fiber. Most common repair list if this happens would be new chain, new rear D, replace some spookes and rear D hanger. So yes spend the $30 on a new KMC chain....

Ok I have a chain and cassette picked out see image for part numbers. If I spend another $20 I save $10 on shipping and I also have a 10% off code.
Any other suggested consumables I should consider ordering now and just saving for the future?
Thanks all for the tips hopefully the new cassette will help make climbing a little easier as I don't often use the big gear much so it won't be a huge loss.

Tubes? A tire? Chain tool? I like to have at least one spare tire in the garage at all times. I'm about to pull my one spare out because I found two chunks missing from my rear tire. Time to order a new one.

You need an intermediate length RD to run a 32 or 33 (SRAM WiFli, not sure what the Shimano nomenclature is) Mountain bike long RD to run a 36. XTR is a mt bike setup.

I just have the one road bike, so I keep an extra tire, tubes, brake pads, brake cable, derailleur cable and KMC quick links on hand so that I can get my bike back on the road quickly.

I keep about 4 spare tires on hand at all times... some of which may or may not be mounted on the spare wheels that I also keep on hand at all times. 
None of that light maintenance is hard but give yourself extra time the first time you do it.

One tire will put you over. Do you keep an extra on hand in case one gets damaged? Or a bottle of your favorite chain lube?

With the new bike you probably don't need to stock anything except a couple of tires and tubes for a while. I broke my rear derailleur cable a few months ago, but my bike is a 2008 that I bought used in 2013. I had close to 5,000 miles on it myself at that point and have no idea how much use the bike had before I bought it. I do carry a KMC quick link in my seat bag. Haven't needed it myself but I was happy to be able to give one to a another rider once that enabled her to get home.

The purchase for me was more form than function.... the XX cassette is a work of art... I wanted the bike to have a certain esthetic... but next time around likely I will go cheaper..
I actually had a similar setup on my prior road bike... recommended by a fitter since I tend to spin alot; I really can't mash because of some issues with my left leg (nerve damage). Plus I was doing alot of mountain states touring at the time and the mountain bike gearing was essential. With the new road bike, I knew I wanted and would need a similiar setup - I've gotten use to riding with the low gears (plus I mountain bike alot so my pace an cadence is similar).
And LGHT... I am old and saved 10 years to have this last bike built, so the cassette expense was the least of my worries. Just for grins and giggles, check out John Slawta's facebook page - Landshark Bicycles... now if I can just ride to the level I should with this cool bike...

I have a new Ultegra 12-30 cassette and new chain waiting to go on the bike. This makes me feel better about myself.

SoCal GMR Ride - March 8 - UPDATED DATE
I may opt out as looks like I likely will be sole woman. Knowing who is riding and how much faster they are...I'd be riding alone most likely. Hate to make anyone feel like they need to ride slower or wait for me. Maybe wait for a ride where some of my lady cycling friends are available too. I'm officially on fence now

I won't be going either; I had a bad reaction to antibiotics (cipro) and my knees are toast. I had to stop biking for 3 weeks and started using a cane again.
