if i were you, i'd go with the most hardy of those fish, or the cheapest. even right out of the cycle, parameters can still unexpectedly swing, so i'd wait a week or two for the inverts, but thats just my two cents.
also, it's not on your list, but i think a royal gramma would be really cool in that tank. well, it kind of is..it is a basslet. and one last thing, worker fish are the best fish, so i'd definitely do a blenny, to eat up some of the algae, imo its nice to have fish that help keep the tank clean.
