I think even with the fuge you are pushing it. I wouldn't say you need to take anything back to the LFS
if your parameters are stable, but, even on the short side, you have about 22 inches of fish which (if you use the common 1" per 5 gallon rule) would mean you would need a 110G tank just to house the fish you have right now.
That being said, I do know of many people that have REALLY overstocked tanks, but they have extra filtration going and stay on top of their water changes and they have no issues.
Everyone has their opinion on the correct amount of fish, but if you constantly check up on your tank, you can get away with more.
Just my $.02
