I seem to be more conservative around here when it comes to stocking levels, but I think it's safe to say that's too many fish. What to leave out really depends on what type of fish you want to keep. If you want to keep the pair of clowns, I'd just add the 3x chromis and the goby and call it quits. Like Mike mentioned, I wouldn'd attempt the Angel with coral in there.
I have a 46g, with 1x clown, 1x Bangaii Cardinal, 3x Chromis, and a little Yellow Clown Goby. For me, I can't imagine adding any more fish.
