Dan,

A couple of things to try to get a more authentic sound out of this tune:

1. Don't put the piano solo in the left channel while comping is going on that is in the center. Sounds like two piano players which is almost certainly never going to happen in a jazz combo.

2. To rescue the vocal track - comp the best parts of your two tracks into a single track. Doubling is almost never part of a jazz combo recording. In fact, I can't say I've ever heard it before in a jazz combo. Also, high pass that vocal at around 250 Hz or so and much of the popping will disappear.

3. Delete the count-in.

4. When you track the vox next time, step back away from the mic - after getting your pop-filter or making one yourself with the classic women's nylons over a needlepoint hoop/bent coat hanger, etc.

D does seem to be better for you. Try sliding into and out of the notes somewhat; relax. Dance a little while you're recording - feel the song while you are singing it - it will show up in the recording as feeling less stiff.
