Get at least one Sure SM57 mic, great all rounder and also very cheap. In fact you will find these in all top studios - one of the staples for recording live guitars.

Any particular reason you are going with the DP01? If you are just starting, I would suggest investing in either Protools LE (to start) or Cubase SX3. A good soundcard like an M-Audio Delta 1010 will give you enough inputs to record a drum kit live and you can alwys get a cheaper Tascam US428 (you don't even need a soundcard to operate this) to act as a DAW controller for editing within Cubase and Protools. Depends on what you are looking for. Just saying if it was me, I'd go the software route. Hardware stations are great in theory but can be quite limiting - depends entirely on the type of music you intend to work with...
