Whoa, that's alot of questions
Quote: So the only thing i will need is etc. Studio Konnekt 48 or M-Audio Profire and good mics ?
you first need to define your needs! those sound cards/audio intefaces are real killers, but maybe you won't need such powerful interfaces. especially if you're only going to do one instrument at a time.

What is VST?
What is MIDI?
vst are usually virtual effects, and VSTI are virtual instruments (like a software simulation of a famous keyboard)
Midi is a whole can of worms, but basically it's what allows you to pilot stuff on your computer with an external controller. (it's much more than that but that'll do for the moment)
Quote:
Do i connect the interface to my computer ?
yes it's connected to your computer, either by USB, firewire, internal card and breakout box, or just an internal card (in which case it's usually refered to as a sound card. the distintinction is sometimes not clear)
Quote: Another question: How is it best to record drums ?
drums are one of the hardest things to record. to do it correctly you need multiple mics and multiple inputs on your interface.
