I agree completely with Bridgeman, but I would think you will be fine with one circuit.
Is your run to the back outlets and 7 lights 14 or 12 guage wire (a 15 or 20 Amp breaker)?
Even if it's a 15 Amp run, what is the wattage of the lights bulbs you are using? If they are 60W each, that's 420W total for the lights. 700W if they are 100W bulbs each.
A 15A breaker gives you a max of 1800W (P=V*A, = 120V * 15A). You should stay under 1500W to be safe. Most projectors are easily under 500 Watts, some are higher but you should have plenty of current for the lights and the projector if that is all that is on the run. Just add the wattages up.
I've got just about ALL the lights for my basement (not just the theater) on one breaker. And all the theater equipment (Receiver, DVD, TiVo, Projector, Subs) are one one dedicated 20 Amp circuit.
