Here would be my general recommendations
Filtration:
Live rock, and a decent skimmer. Are you going to have a sump? Is the tank you got drilled for an overflow?
Flow:
The more the better for the most part. Look for stream style pumps. If you want to start off cheap, I would grab two koralia 1200's for your tank. Could do slightly less for soft corals or slightly more for SPS.
Lighting:
Depends on what you want to keep but I would go T5, metal halide, or LED. If you go with T5, I would use a 4-6 bulb fixture again depending on coral type you plan to keep. ILook for individual reflectors and a decent brand bulb is ATI.
Heaters:
Can use anything that you feel comfortable with but I prefer titanium heaters.
Use an RO/DI filter for all your water, and don't add any supplements that you don't test for. I would get a refractometer to check salinity, they are really the only accurate way.
As for test kits, you will want ammonia, nuitrite, and nitrate initially to monitor the nitrogen cycle and see when it is safe to start adding livestock. After the cycle, we don't use those much but you will want to monitor alkalinity, calcium, and magnesium once you have corals. Stay away from the all in one test kits, they generally aren't all that good.
I would stay away from canister or wet dry filters, they really have no place in a reef tank (saw you were looking at some in the classifieds section)
Do you have a good LFS you go to?
