I'm seting up for a 30-40 mile commite, and I have most of what I want and need, but what pump should I get. I do a LOT of miles, and so far no flat, but my LBS said I should do this! Well should I get a CO2 pump or a plan old pump or both? What model, how much, ect?

if you get CO2 be sure to get oen that will use several different cartriges. non threaded ones. then you can buy them at walmart dirt cheap. myself I prefeer co2. is far faster to get you up and running. but when you get to a pump deflate the tire and fill it with air.

I don't mean to be rude, but you should probably do a search of the forums. This topic has been discussed quite a bit in the past.
I'd use CO2 for fitness rides, events&races (due to weight, size and that there usually will be support available if I flat out more than twice).
I bring a pump commuting and touring. Your pump needs will vary from others (size&pressure). I've had decent results with the Topeak morph range-but have had to change the head once, as it wore out.
Both. CO2 makes it easy to get full pressure, but if you have multiple flats, you never run out of pump.

If you can handle the space/weight, do both for a commute of that lenghth. The pump should have a flexible nozzle (minipumps are hell on stems). You can use the CO2 if you need to inflate in a hurry or if your pump breaks (for example, if it won't seal). If you can do only one, the pump is the better choice for commutes. Problems often come in series, and CO2 runs out.
CO2 works well for racers because it is fast and because racers have backup.
I like to use a minipump to inflate the tire up to about 30-40 psi then add CO2. This way, I can make sure the tire bead is properly seated without blowing the tube. It also allows me to use the cheap 12g CO2 cartridges from xmart and still get full pressure.
