You need to mic the drums seperately. If you don't have a mixer and individual mics, use whatever you have to mic the snare, hihat and kick seperately, and then use a couple of mics overhead for the cymbals.
Record the whole band, then go back and re-record each instrument seperatately. Start with the bass so that the kick melds with the bass notes.
Record the guitar next so you can double it up and make it stereo.
If you have keys, add em last.
Then do the vocals. Start with a scratch vocal so you can add harmonies, then redo the main vocal until you have it perfect. Even if it means doing each line seperately.
Use a click track too.
When you mix down, spend a whole crap load of time on it. Like 10 hours to get the sound down.... especially the drums and bass.
