Welcome to the club.
For your tank size, I think the Compact600 should provide sufficient flow. If you want more flow, you could consider replacing with a bigger pump (ie. Compact1000) or if you choose to use wavemaker, maybe can consider RW-4 or MP-10.
I would seriously advise you to cycle your tank before adding any livestock. IMO, dosing bacteria may help shorten the cycling process, but that doesn't mean it can replace the cycling process completely. Adding any livestock to a tank too early, will only stress them, worst case kill them,....life loss, money loss. Another scenario is if the fish develops ICH, then you will have worry on subsequent additions. Have known reefers to give up the hobby when ICH proves too much to handle.
Whatever your decision, Happy Reefing
