Unfortunately we're all bombarding you with tons of information at once. Probably because we're just as excited to "create" a new tank, like it were our own (but not our $$ lol).
With the lighting Issue, again, T-5's have advantages over PC bulbs. You'll also be getting more light for your money with PAR, (like I mentioned to you before) with them as opposed to PC bulbs. If you can find a great deal on a used PC fixture, go ahead and snatch it! But if you have to buy new, T-5's will probably be a better investment in the long run...
As for the substrate issue, read some articles on RC about DSB (Deep Sand Beds) vs. BB (Bare Bottom). It's a controversial subject here on Reef Central, because many people have strong opinions on the issue. Take advice from people who have had tanks with different substrates over the years. I can't really speak about numbers or percentages, but many people here agree that over time, deep sand beds accumulate crap in them, which cannot be broken down by bacteria, nor can it be removed without removing the sand itself. Sand stores lots of waste to fuel algae and crash aquariums when it's "full" of waste. (If you see a tank with a DSB, look for little grey collored layers of filth within the sand bed).
If you like the SPS small poyped stony corals a lot, going barebottom (no substrate) will be better for them, as they like cleaner water. If you like a lot of softy corals or corals that feed more than others, sand will benefit them, as they like dirtier water and the microorganisms provided by the sand. If you want something in the middle, a mixed reef, or you like the look of sand but don't want the huge problem later on, go with crushed coral. It looks great like the sand, but you can actually clean it by vacuuming it. Just like you would for freshwater gravel.
Ideally, before you purchase equipment, like the substrate, you should have an idea of what you'd like to take care of in the tank. Even look at others' aquariums and pictures. If you figure out what corals you would EVENTUALLY like to keep, you may as well get the proper equipment for them from the start...
You might not want to hear it, but the best thing you can do is start reading on many different forums on RC...
