Scott, your settings sound great indeed!

I would like to add a few words more of comment, speaking not of "punch" but of better and authentic live feel.
What I do, to achieve this, is to mute all those style tracks that sound canned and boring: a typical example is the acoustic piano playing chords in the same repetitive way on Swing styles. We all know that no real pianist would play chords in the same way, on the same beats and with the same accents throughout a whole song! So, my suggestion is: try to rely only on a few tracks, like drums, bass and whatever else sounds authentic to you, and add rhytm sounds like piano, electric piano or guitar with your left hand. We know already that some of us mute also the bass track and play the bass line with the left hand; if you are lucky enough to sing well, you could then play the chords with your right hand, otherwise you have to make a choice...
Also, in styles like Bossa Nova, mute those darn strings that play in the background (they are so corny!) and also those flutes... (yuk!)

These are just a few examples or suggestions: your individual taste should of course be your guide.
