Another "Nano-er." :)
Since you are doing FOWLR (Fish only with Live Rock), lighting is not a big problem. Good options are Sattelite Fixtures. You can do a single-strip instead of double-strip. But, if you decide to do corals, a single-strip may not be enough.
Good low-light corals are Zoas, Mushrooms, and Polyps. Good begginer corals as well.
You can have two fish in that tank easily, as long as you are good with water changes. That way, a skimmer is not needed. Inverts should consist of snails, hermit crabs, a few crabs (Pom Pom Crabs, Porcleian Crab, Emerald Crab are popular), brittle stars, and shrimp (Skunk Cleaner, Peppermint, and Pistol are popular). Fish could be many things. Clownfish, Gobies, Pseudochromis, Royal Gramma, Firefish/Dartifsh, etc etc. Name some you like, and we can help.
I would definately mod the AC110 into a fuge. Here is a good link for that: http://www.reefcentral.com/forums/sh...hreadid=679159
