Well Bob said if we thought any monsters need loot/difficulty tweaks we should find out the messed up ones and post em. I'll start.

-Lava Serpents, they hit too hard and have too much health for the 300 gp they drop. They actually have the potential to kill you if your not careful.

-Lesser/Greater Goo. Wtf is about all i have to say. Lessers arent that bad but they still should drop slightly more gold. Greater goos should be made easier and drop a tad less in my opinion.

I'll post more as i find them, and feel free to add whatever your opinions are. The more the better.
