I would just start with the live rock and live sand with a couple of damsels and let your tank cycle for 6 weeks or so before you spend your money on the clowns and annenomie. Make sure you use R/O water from your lfs it will help the cycle go better. You might also want to take out the bio balls and replace it with some live rock chunks, it will help cycle quicker.
