More bits means:
• Less quantisation noise, so your noise floor is a bit lower and therefore, when you're mixing stuff together, you accumulate less noise
• More numerical room to play with, you can scale or shift the volume up and down more without clipping and with less loss of accuracy
With 16-bit CD audio, you can't just convert to 24-bit and suddenly have less noise. You might get more room, though.
As for higher sampling rates (more kHz, if you will), I think Monty mentioned some benefit regarding less sharp aliasing filters (can have a larger transition band from 20–48kHz, say, rather than from 20—22.1kHz), but it's not something I understand the benefit of well.

filters with a sharper cutoff will 'ring' more, smearing sharp changes in the signal out over time. It's a pretty subtle effect when it's all happening above 20 kHz though
