As far as rear suspension is concerned, there are many different designs still out there. Some have pedal bob, others claim not to. I've never ridden a full suspension bike (besides the junk from x-mart) so I can't comment on the good designs.
Having done mountain biking on rigid forks, cheap suspension forks, and GOOD suspension forks, I've decided that front suspension isn't worth having unless it's a good quality fork that doesn't weigh 5 pounds. A rigid fork is so much better than a cheap heavy suspension fork.
