When left to myself to do the layout, I usually do something I haven't seen done much in residence wiring: keep the lighting and receptacles separate, even in other-than-kitchen areas.
We just finished roughing-in a small 3-br/2ba house; we placed the bedroom receptacles (12) on a single 20-amp circuit, and the bedroom and bathroom lights and fans on a single 15-amp circuit.
Likewise, we placed the livingroom receptacles (6) and the hallway receptacle on a second 20-amp circuit, and the living-room, kitchen, hall, and exterior lights on a second 15-amp circuit.
A small advantage of the single bedroom receptacle circuit is the need for only a single AFCI breaker (1999 NEC). By the way, has (or will) anyone come out with an AFCI feed-through receptacle?
By saying "I also beleive in keeping lighting and power on there own circuits.", NJ may have meant the same thing, in which case I'll give him credit for mentioning it first.
