before everyone gets in a tizzy, if you delete the period from the link it works
now down to bidness: a skimmer would be my first purchase. look into the AC Remora...its a really good HOT model...should set you back a couple hundered bucks...
what sort of lighting have you got on there? it looks pretty bright, but the hood looks like your average flourescent striplight, which isn't going to do it for a reef
the canister is going to be good for moving water...not sure how many gph it does, but in combination with the powerhead (maxijet?) you are going to want to push through around 550gph in theory
looks like it could use a few more pieces of LR to me...maybe arrange it something less like a clump, but of course that is a personal preference thing, its all about what you are trying to recreate...have you secured them together manually? or are they balanced? either way, just make sure they are stable!
looks like its coming along though! get that sg down to 1.024 or 5 ish and you will be cooking with grease
