1. Yes too much headspace. You could split into a 3gal and a 1gal or four 1gals. Never seen a 2gal. Alternatively you could add a gallon worth of sanatized glass beads (or similar) to bring the liquid up to the neck of the carboy.
2. I do all my secondaries as 5 or 3gal plastic water jugs. The blue ones they sell at walmart. There is some argument over oxygen permiability, but i've never noticed a problem and dont bulk age in them.
