The 32 if I had to pick. Definitely not the NTK, which will put too big and sloppy of a sound in the monitors - making it harder to fit in the mix. Also, compared to what else is on the market, it's just not that good of a mic.
The DMP3 is a good, clean preamp. If you pair it with a 32 you're going to get squeaky, clean sound and for what you're doing it's going to lack personality - and if you're trying to get any kind of "edge" - forget it. That 32/DMP3 combo would be cool if you were recording bluegrass or traditional music with lots of acoustic instruments, but for what you're doing I wouldn't recommend it.
I'd get an ADK Vienna over the KSM32 for rap vox. The Vienna has a little bit of color and "sheen" in the high-mids, compared to the neutral, bright 32, and the mids are smoother on the Vienna. And the Vienna is half the price of the 32.
