I prefer canister filtration. They're very industrious b/c they filter a LOT of water.
You seem extremely young to this hobby... If I were you, I would hop over to the local bookstore and invest in a couple of good books. They help you put on your swim trunks before you jump in the water, so to speak.
As far as the price list you have... it seems fairly reasonable.
Here is my advice for your setup...
1. If you can buy a larger tank, do. It is much better in the long run.
2. Use sand as a substrate and be sure to have at least a 2in layer for nitrification reasons.
3. I would skip on the canopy. You may not want to go reef anytime soon... I know I didnt when i started, all I said was "I just want some fish..." well, about 3 months after saying that, I went reef, and my origional investment in a "canopy" turned into a $120 piece of firewood. Just go with a glass top. CustomSeaLife makes some nice PC/MH light fixtures. Check them out.
4. Always shop around. And buy that book.
5. Ask us if you ever have a question... there is nothing better than the opinions of others when in confusion over something.
