I'm building up a cross bike with lots and lots of spare parts and swap meet stuff i just picked up. I'm lost as to what kind of gearing i should use, not a lot of hills around here. MTB or road cassette in back? Up front?

you can use whatever you need but most run anything from a 36 to a 50 ring up front, usually a 36-48 or a 38-50, you can even run a 53 if you want to. Then get a 12-25 cassette which should cover most riding you want to do. Unless you are going to go off-road and climb some real MTB typr trails you won't need anything else.

I'm in agreement with climbo. I was running a standard 39/53 Ultegra on the front and a 12-25 on the back. I just switched over 2 weeks ago to a 12-32 XT on the back cause I found I wanted to take my CrossCheck more offroad and I was having trouble keeping my cadence up on the climbs. You'll need to go to a mountain (LX/XT or equiv.) derailleur with a longer cage if you go to a 32.

If you are mixing road and MTB stuff check with your LBS for compatibility - you can find that you need to get the right chains for the cassettes (eg HG/IG/Sachs) or you could have shifting probs due to teeth profile differences. Not a big issue, but annoying if you get it wrong...
