I wouldn't put fish in there just for the sake of putting fish in LOL. i would stock slowly and deliberately, once you get enough fish that's it so make sure they count.
I wouldn't automatically assume the damsels will be an issue, but it's the most likely outcome. Maybe yours will get along with others, some have them and they aren't evil.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
