A good pair of mics for recording a live band at FOH, DAW controlers?

Well, after many hours of research I have decided on a FireStudio Mobile for my first interface. One of the things I plain on doing is setting up close to the Front of House position (FOH) and positioning a mic on both sides of that area. With the extra analog inputs I will probably experiment with some direct outs, subs maybe?
I have 3 friends that have house gigs and they are OK with that. The management is OK as well so, as far as I know I just have to get the "talents" OK.
Any suggestions on what mics? I am looking for cheap but decent quality.
Would small diaphragm condenser mics work?
Also I have a Mac Book Pro and a Mac Mini, will I be able to install the software that comes with the FSM on both computers?
