Help on wiring and circuit breakers

So I'm working on wiring my garage in and wanted everyone's input on the "best" way to do the wiring. This room is going to be used mainly as a theater/media room, keep this in mind when providing input, thanks!

So I've attached a jpg of what the room looks like and some dimensions.
Key:
Grey - Circuit Breaker
Yellow - Lamps 1&2 wired together on a dimmer
Lamps 3&4 wired together on a dimmer
Lamps 5&6 wired together on a dimmer
Also want 3,4,5,6 to be able to turn on all at once with a switch aside from the dimmer.
Light Purple - Media Center (Computer, Dvd, Stereo)
Blue - Tv Setup
Light Blue - Mini Fridge
I will have a drop down projector in the ceiling, a drop down screen over the tv, and a ceiling fan.

Please provide any and all wiring tips. Including breaker size and appliance separation.
