Brings back memories of when I started recording
I could write for an hour on this, but I'll keep it brief.
Most bands use application specific mikes there dude. You got a nice mike for 35 quid (that's a day's pay where I'm from), I'd say use that one for your vocals.
Drums can get away with a minimum of three for decent quality - one (usually an expensive dynamic or a lower cost electret with good top end response) for your cymbals, one (a dynamic with a flat midrange) for your snare/toms and one (a dynamic, usually expensive, with a response down to 30 Hz) for the kick.
In a pinch, I used an AIWA cheapie that came with a reel to reel recorder for drums once for a live gig - very cardioid, very good bottom end (25 - 5000 Hz measured response) and impossible to overload.
Miking your guitars, look for a dynamic with neutral response and no peaks anywhere.
Miking your bass, use the same type you would for your kick drum.
General rule of thumb, dont put an electret mike anywhere you wouldn't put your ears. Electrets are less expensive and give awesome performance within their specifications. They have the disadvantage of lower dynamic range, requiring power and can be noisy. Dynamic mikes are quieter, tougher, have a better dynamic range but tend to have a less than flat and more limited response and aren't as sensitive.
As for recording, if you studio record at home only, go for the fastest computer you can afford, with the biggest HD you can get. A Yamaha DS-XG series sound card will never wrong you either (stay away from SoundBlaster - their noisy). Most software to start you off is available FREE.
If you need portability, try a Roland or other HD recorder. Stay away from cassette multitrackers other than for maybe using it as a "notebook".
That's my tuppence
EEEEEK!
