A tank with a lot of bottom feeders isn't a bad thing, as long as you feed keeping in mind that most of your fish aren't going to come to the top to feed. My 29gal and 55gal are both bottom feeder heavy and I just make sure I keep my substrate clean and feed more sinking foods than floating.
HOWEVER, as interesting as that stocking lists sounds, Fishman, you're going to be SEVERELY overstocked. Drop the two pictus (they're not suited for your tank anyway...they get to be 6" and are VERY active) and add another panda garra (they prefer to be in groups of 3+) and I think it's perfect.
The only REAL concern I have, other than the overstocking and the pictus being too large and active for your tank, is that the panda garra and the pearl danios are both very small and kribs can get pretty nasty when they go into breeding mode. I would say rethink the krib pair and get two females instead.
