Basically what my title says. What are all the tools I would need for a full tune up? And I also need a good guide/tutorial for learning the know how of doing this. When listing tools, please use the tools proper/original name because I'm not too familiar with shorthand and slangs.

Park tools has the big blue book that's pretty useful. There website, linked here is also pretty good, as is the late Sheldon Brown's site, here (just ignore the crappy web design and look at the content).

too much to post.

Lots of helpful videos there.

As others have implied, this is no small request. All of the following are subjects unto themselves.

Learn how to adjust your derailleurs. The manufacturer of your groupset should have online instruction manuals.
Learn how to inspect and adjust your brakes.
If necessary, learn how to replace your brake/shifter cables.
Clean/inspect your drive train. The chain will probably be the first to need replacement. Learn how to check it, clean or replace if necessary.
Inspect the crank set; see if it spins freely with the chain off. If not, find out how to pull it apart, what to clean, how to inspect for wear, where to apply fresh grease and how to put it back together.
Check your tires for wear.
You may want to check with an LBS about servicing your hubs, if it's been a while. If you're ambitious and you don't mind grease, you can tackle this yourself, too.

You can take care of a good amount of the basics with a couple screwdrivers and a set of allen wrenches. If your bike has a lot of carbon bits, you'd be smart to get a torque wrench. Even if your bike doesn't have a lot of carbon bits, it's still a good idea.

For a full nontrivial LBS tuneup, you will probably need at least $70 worth of tools, and a bike stand makes it easier but is not essential.

You can however, do the quickie type bike inspections with non-breakdown cleaning, and quick adjustments of brakes & derailleurs in 5-10 minutes with almost no tools.

Not really trying to tune up an old bike. Just purchased a Kestrel RT800SL Full Ultegra Set on BD. Seeing how most who have bought a bike from BD required a Tune-up, not just assembly, decide to learn how to do it myself. Not too worry about the learning curve because I have experience dealing with asembling some parts and mechanical stuff, mainly more concern with getting the proper tools.

Also, do you use the same lube for the chain on other parts that require greasing/lubing? If not, can someone tell me which type of lube/grease is used on which part?

Here's a question gear towards BD customers. Honestly, do I need to overhaul the parts on my bike from BD when it arrives or just a simple tune up would be fine?

you'll need to look over everything. For example, my bike's bottom bracket wasn't torqued all the way. You'll still have to adjust the derailers, tension the wheels, redo hoods/bar setup, grease various bolts. yeah, everything

All of your questions can be answered with a quick google search. They aren't obscure questions.

Way to be lazy though.

+1 you can google all of these questions. Oh, but then you wouldn't need BF.

mine was pretty straightforward. i got an rt800 and we basically just bolted everything on and rode. Make sure you use carbon assembly gel on everything if it's carbon.
