Welcome to the site.......
I would add another 20-25lbs of cured live rock right now if you can......while you qt your new additions. This should be all cycled by the time your fish are ready to be added. I have gone the non-qt route and have regretted it as I lost a bunch of fish once. I wouldn't necessarily take the lfs at their word as they are not always aware of the fish they are getting in. Some may have been exposed to such things as cyanide or added stress from collection methods that may not show up right away. I always ask the lfs to feed any prospective fish to ensure that they are eating prepared foods and are ready to come home. I have had them hold fish for up to a week to make sure they are eating and healthy......
Fish suggestions for you...hmmm...I would avoid damsels as they are territorial and aggressive and have no place in a community tank.....in a dedicated damsel tank yes but not with docile tank mates. I would look at some sort of wrasses and lean towards fairy wrasses and coris wrasses, six lines can be aggressive (at least mine is a real little meanie) cardinal fish such as bangaiis and pyjamas, small pygmy angel fish *my personal favorite fish* a pair of clowns, such as skunk or tomato clowns are different.....please refrain from getting an anemone for these as it is not needed and there is no guarantee they will host it anyway and your tank is too small and young to support one. Any of the gobies are nice such as a citron/clown or watchman gobies, blenny such as midas or bicolor.....all great fish. good luck!
