Goodness. . .skilters and wet/dry filters for a reef tank. I feel like I've just stepped back in time. Sk8r has given you some pretty good advice, so I'd go with that. If you're going to spend your money anywhere, spend it on the skimmer. You don't have to spend $600, but don't get a cheap one either. I have an Octopus NW-110 for my 46g which I really like. It'll run you about $150. ASM also makes good, affordable skimmers. There are many others, but all of these will require a sump. The sump I would highly recommend. I believe most bowfronts use tempered glass all around, so unless you can confirm that the back glass on your tank is not tempered, drilling is out. You can still add a sump with a hang-on-back overflow. Lifereef makes a very good, worry-free overflow. They're much more expensive than something like a CPR overflow, but knowing it's not going to fail on you is well worth the extra money. The sump you can build yourself out of a used tank (I used a 20g long tank for mine) and some acrylic for baffles. It will probably cost you about $20 or so, so it's up to you whether or not it's worth the savings.
Anyway, it sounds like you're off to a good start. Try your best to take it slow and get everything set up the way you're going to want it in the long run (tank, stand, sump, lights, rock, sand, plumbing, etc.). Re-doing just about anything involving large amounts of water and living creatures just sucks.
