As said before, anemones need much better lighting than a fish only tank, excellent water quality and a mature stable tank. When you said that "they eat the microscopic lil critters for cycling" did you mean the anemone eats the bacteria? Because they don't. They will sometimes take plankton, and of course they use lighting, but they also require regular feedings of meaty foods.
Featherdusters are a great choice and are very easy to maintain. Try to avoid the coco worms though....they have nice colors but are harder to keep alive (coco worms have a hard calcerous tube rather than the softer "paper" looking tubes of the common featherduster).
I have no idea what you mean by "grey looking mud skippers"....
Wayne has an excellent idea by putting all your equipment behind eggcrate and hiding it. If I could do one thing different with my own tank, it would be to use a sump or some way to hide all the crap that the tank requires!
Be careful with your choice of fish. Dominos are beautiful active fish but they are probably the most aggressive of the damsels. If you wish to keep one or two of them, then you need to think out what other fish could possibly go with them safely. What you need are other fish just as aggressive as the dominos or possibly more so like one of the dottyback species, or fish that have other means of defending themselves like foxfaces or dwarf lions. You will also have to determine the best order of introduction too, depending on the aggression level of each fish.
And boxfish? Nice fish, lots of personality but better off kept in a species only tank as under stress they can release a fatal toxin that can wipe out your tank. Cute things though....if I had room for another tank I think I'd get one of these guys (I love the way they hover around!)
