Yo Coughing One:
I'm guessing that you have only 4 tracks? I hope you have 8 tracks.
With only 4 tracks, you can use three for the band and save one for the vocal.
If you have to bounce tracks, well, you will lose control of the individual tweaking of, say, the bass track. If you bounce the bass and keys and drums to one track, however you tweak it when mixing you can't tweak each sound; so, what you would want with the bass probably won't work too well with, say the drums.
The more mics you have going, the more difficult it becomes to get a good cut unless you are in someone's studio paying for the service.
I always like to get the meter down first; like drums. Most of the time, I do keys with drums. Then, bass; then, whatever else I dream up. Sometimes one track has only a cymbal splash or some sound from my synthesizer.
But, I always like to do the vocal last. This way I can trim the sound of everything and keep the vocal up front. If I have a couple of tracks, I sometimes put the vocal on two tracks. But, with a good mic pre, this isn't always necessary.
Get in there and record and experiment.

PS You can almost always let the singer hear the reverb; but, you don't have to have reverb recorded with the singer; you can add it or tweak later when you mix.
