My first SW setup was a 55 with a 125 skimmer, 65 lbs of live rock, 2 60 gallon HOB's, and 2 200 GPH powerheads so I was pretty much where you were, even living in Ohio. I checked out a snowflake as one of my first choices, but they make a terrible mess, and bio-load gets pushed so I passed on it. If you do go with the eel keep in mind you will be doing a lot of water changes. I don't think your equipment is unnecessary, in fact I think it sounds good, but I think you should use more live rock and invest in some powerheads.
I used the powerheads for extra flow on my soft corals, it helps them get food and if nothing else it makes them sway more beautifully in the water. Good luck!
