I used to use a UA Solo 610 to warm up mono samples from my decks before hitting the MPC. I was running a line out from my DJ mixer to the preamp.

You will have to A/B both channels to find the best quality mono sample...can be very time consuming, but also very rewarding. Much easier with an interface with multiple I/O, as you can bounce mono stems through the preamp and A/B in a DAW.
Possible, but not the best way....also, preamps will "colour" not clean-up your sounds. Lamp nailed it, though. Best bet is a DAW/Interface and some decent onboard/plug in EQ/effects.
