My guess is most will tell you to ditch the fluidized bed filter, the bioballs in the wet dry, replace the skimmer that comes with the wet dry, and ditch the uv sterilizer, as the fluidized bed and bioball filter will not offer you any anaerobic filtration and will be a "nitrate factory" (meaning the aerobic bacteria will convert everything into nitrate and the tank won't keep up with breaking the nitrate down and removing it from the system), attached skimmers are not very effective, and you don't want a uv sterilizer on a reef. Next you'll be told 75 lbs is not enough live sand, and you need more live rock.
Here's my first question before I critique, what are you going to house?
If you're going reef (and it seems you are with upgraded lights) I kind of ride the fence on removal of aerobic bacteria filtration. In my reef, I use an oceanic trickle filter with the bioballs removed (it aerates the tank) and I also run a uv sterilizer, I don't have a DSB (deep sand bed - used to process nitrates and facilitate their breakdown into gases which bubble out of the tank), and my live rock is self seeded dead rock. In my non-reef pond (which has MHs over it vs. PCs which are over my reef) I have a trickle filter with bioballs in it, a DSB in my refugium (pretty new, though, only a couple of months old), macroalgae for nitrate exporting in the refugium, and a lot of store bought live rock mixed with my seeded dead rock, there's also a moderately deep sand bed in my actual pond part, with about a 3" bed.
I haven't really given you any suggestions yet, but here goes. If you are going with live sand, it would probably help to increase the amount of sand so that you have between a 3-7" deep bed. If you are going with live rock, you can either seed some dead rock or add more live rock, although you may have enough already. The uv sterilizer you may not want to have depending on how many fish you keep (I keep tons of fish in my reef). I would keep the bioballs and fluidized bed filter in only if you are going to have a lot of fish, although if you convert to a DSB, any nitrates that are produced should be broken down without a problem. Also, the more lights you can fit at once the better, so you don't have to upgrade later on.
