If your room isn't great sounding or your vocalist's voice is a little thin, or bottom-heavy, or whatever, after your preamp you might want to have an EQ just to clean things up a bit. Make sure this is before the compressor, otherwise you might be bringing the problem areas up in volume. After that, some compression (very light, try to correct dynamics mostly by working on mic technique).
i strongly disagree. i would never EQ before compression.
i would also never track with compression, unless i can't get a reasonable volume-to-disk without clipping on the louder parts (remember, if you're tracking at 24bits, the v-t-d doesn't need to be THAT hot!). in which case, i'd use very very mild compression, just enough to squeeze the part into the dynamic range of the medium but without leaving a substantial sonic footprint on the track.
getting a good headphone balance is one of the most important things to getting a good vocal performance. i'm not going to tell you how to set things up in a technical manner, because quite simply that's totally impossible - so many variables - the room, the mic, the pre, the song, the singer etc etc etc.
if you're singer isn't feeling comfortable with the 'phone mix, they will not produce a good performance.
try and get as many takes as the singer is capable - but remember, the singer will only have a finite number of takes in them. sure, they can keep on singing all day long (or can do a 3hr set), but their voice will probably start sounding fairly tired by (at the most) the 10th take. so make sure you get enough workable material quickly.
if there's a problem area, then work on that part. don't re-take the entire song because of 1 problematic bridge or wtv.
singers often need some ego massaging. they're sensitive human beings, so tell them it's good when it's crap and it's awesome when its ok, but "could we maybe try another take?"
as for mic placement/choice, preamp/compression/reverb settings...use your ears.
