Personally I'd skip the eels. I've had eels before, specifically a pair of golden dwarf moray eels, they were great but after awhile I couldn't keep any smaller fish with them. Blue Spot Jagdish, gobies, etc.
On the fish side you can't beat a pair of candy basslets. You'll pay a premium but they are rock solid and drop dead gorgeous. I've had a pair in the past and I'm definitely adding a pair to my current tank. The avid reefer will be jealous and your novice friends will be like what the crap.
I'd also offer a pair of borbonius anthias but if you want a small shoalnof other anthias I'd skip them.
Also something cool to do with a smaller and even larger tank is a group of barnacle blennies. They are a lot of fun to watch.
Good luck.
P.S. If your wife wants an anemone for the clowns I would get one but get a nice one; they are spending but gorgeous.
Skip the feather start they are impossible to keep long term.
