pics of the setup would help out a lot, but assuming you're using the ProClear like it is out of the box, I'd remove the bioballs and extend the Drain down using a piece of PVC down below the waterline. That should help eliminate some of the sound that comes from that type of sump. I'd replace the bioballs with some pieces of liverock for more effecient filtration, but that can be done in thirds or so if need be.
As far as lighting, if you're doing a fish only (for now), I'd do a single T5 retro kit at first, and if you decide to go with coral later on, you can always add more T5's. Plus the bulbs are cheaper and last longer than power compacts.
Hope this helps
