This is really something that your electrician would be able to address for you if he is worth his salt. Luckily for you, you have the breaker panel close by and that should make the job much easier/cheaper. One great thing about have two or more dedicated circuits directly feeding the life support for the reef is redundancy. If for whatever reason the breaker flips or a gfci outlet trips, you can spread the life support between the different circuits and help reduce the chance that the whole tank looses life support.
Each circuit can feed multiple outlets that can be routed to multiple locations through out the tank. The beauty of this is you can place your power outlets where they are needed instead of working around them. Example you can put outlets above the tank where water would never reach to power controller equipment and lights or near the sump making cable routing simple. You can even have gfci outlets wired so that only the equipment on indivual outlets loose power rather than the whole circuit.
This is really something that needs to be addressed by professionals and I agree that you should be able to get a good idea of the Amps your intended equipment will pull based on the manufacturer info!
