Stellacore - another thing that has come to mind is that I think you'll want to use constant current led drivers instead of fixed resistors. If you ever want (or need) to change the current drive to the leds, a c.c. led driver is the only way to go with this many leds.
You can still vary brightness with PWM - many c.c. led drivers have the ability to vary both current and duty cycle.
