Oxygen "free" copper does not mean that exposing it to oxygen will somehow change it's properties, though oxidation may occur over time. The "free" refers to the lower content in the compound, and there are varying grades of oxygen reduced copper.
I have had speaker wires oxidize as well, but it took them a few YEARS. Wire is cheap, don't worry about it; hack an inch off every year or two, and you are all set.
I use bananas very similar to those posted by Chu, in my HT. In my 2ch system I use Audioquest Type 4, which is solid, long grain, oxygen reduced copper - no connectors.
