Well, the sleeves didn't take me too long, and now this is ready to be put together. It shouldn't be that bad...block, sew the shoulders together, then put in the sleeves, and then take care of the gazillion ends.
EDITED TO ADD: nope, not that easy to do. Length is good, armholes too big, sleeves too small. I think I have to knit a panel instead of just a side seam on the sleeves. So. It continues.
