Soooooo, I guess the reason that my sleeve looked so huge was that I was NOWHERE NEAR GAUGE. Close to a stitch per inch off. I knit loosely, but I didn't think it would be that bad.
I've dropped down to size 5's (from 7's) for the sleeve, figuring that if I've overcompensated I can move up a needle size when I get to the ribbing.
I'll post another photo later tonight when I've re-knit the whole thing........
