It sounds like you got an established tank!
which is great. I would suggest testing all your water parameters a couple of times over the next week or so to make sure they are all good and then you should be good to go! I have brand new Aquapod 12 I am going to set up at work this week with LR, sand, and corals from my 55 gal reef.
I am a big fan of protein skimmers from my years of SW fishkeeping, but don't have any opinions on UV sterilizers-I haevn't ever used one and never had any problems with my tank. As for the damsels, I don't know if you are set on them, but I don't like them-they are aggresive and just plain mean fish and I would remove the ones I have in my 55, IF I could ever catch them!
Good luck with your tank!
