Digital BW, The Print

I use the 10D and have seen slight posterization in
B&W's as well. I'm confused on all the terminology
though... what is 16 bit in PS-CS? I'd love to try... 
Do you first change it to grayscale in photoshop and
then convert it to 16 bit color? I use photoshop 7 on
mac osx. Also I've seen a lot on using curves, is that
better than using levels?
Thanks so much!!
