For cranks, I'd go for XTs if you can. Reasonable price and weight. I think Diabolus and Saint are too much for most people; the arms are freakin heavy on those things. I'm much more likely to wreck a bb than bend the arms.
For wheels, I've had good luck with Sun and Mavic both. The Singletracks are nice for a lightweight set, but I'd go for the MTXs if you don't mind adding a few grams for durability. I've also used Mag 30s with good success but they are too heavy unless you really pound stuff. Definitely they are the strongest rim I've used.
I've also seen 321s and 521s (whatever the new numbers are for those) that have lasted forever. Get a good build and they can withstand some serious abuse. Haven't had much experience with the 823s but I've used 819s for a while and they were great.
A Hadley/Mavic set is sick. I had Hadley on my bike (stolen last month) and it was awesome. Never touched it, it just worked like it was supposed to all the time. Near instant engagement. Nice, satisfying buzz....
