I would definitely go with a protein skimmer. The thing's a life saver. If you can keep the protein skimmer with the refugium then that's the way I would go. This would take out organics (proteins, amino acids, etc) and nitrates/phosphates (via algae filtration). I've got the protein skimmer in the sump, and some Caulerpa prolifera and Gracilaria in the DT (not really a FOWLR or SPS Reef...just a few softies and a galaxea).
Sorry, but lots of people say that they'll get a tank in a year/a few years, and while some do this, others have more important things get in the way (fire, baby, etc.) You might be able to pull off a small rabbitfish and the dwarf angel to help combat algae, but I'm not sure about that...
