Seth, I'm sure any number of people here would be willing to offer help (including me). But it would be helpful if we had more info or you asked more specific questions.
Do you have a preference in lights (MH, t5 fluorescents, led, hybrids)?
Do you have a budget or cost in mind?
Some fixtures are very basic (on/off), some have built-in timers, some have dimmers, some have sunrise/sunset abilities and some have color control. But the costs go up exponentially as you add in more features. And other than being a strong enough light source to keep your corals happy, most of the rest of these features are for human desires and not so much for the benefit of your corals.
As for the sump:
Do you already have the basic sump (tank)?
What all are you interested in having in the sump? A return pump, refugium, a skimmer, filter socks, a reactor for GFO, carbon and/or phosphate reduction?
Good luck.
