the way I thought it always should be is like this:
try the kit your think about
then if you have the cash, buy what ever kit you want to learn.
I bought the mpc 2nd hand with no prior knowledge. But i did have a lot of time to learn its ins and outs - It helps if you have a friend who already rocks an mpc so that they can get you started and show you ropes. its a bit like riding a bike with the stabilizers thing.
EVERYONE: we should be supporting this guy - not being aloof and acting high n mighty.
AS for the drum theory - try the book and if you dont feel your getting the rhythm that you want in your tracks search the forum for a dj shadow article posted on here a while back. It showed how shadow would sample a whole kit with air etc.
More importantly, id say listen to artist that you like and in the first instatnce try to mimic what they do with their drums. (volume, punch layering, diff, sounds, diff loops etc.)- the hope is that you will evolve over time and create your own style using what you have learnt.
good luck man.
