As far as the multiple tracks, you can only record 2 tracks at one time, with the AP 24/96. You could record each part one (or two) at a time, or get a higher input recording card, like the delta 44, 66, or 1010 & 1010lt. these offer 4 inputs, and 8 inputs of analog simultaneously.
There's other sound interfaces that would work, just staying in the m-audio line.
If you're using a sequencer for drums, you could mix down each part of the drum kit to a wave file, then import each part into cubase. I've done this before with n-track and decided it wasn't worth it. I just got the whole track like I want in FL studio, and then export the whole drum track as a single stereo wave file.
