50mm f1.8D or 50mm f1.4 ai'd. Probably leave the MF glass on the F.
18-55 DX. It's a "digital" lens but covers from 24-55 focal lengths and is a very sharp, if a bit slow.
Not to be too much of an advocate for gas, but you could always pick up an F4 for peanuts nowadays, and use your F3 as a backup with a 24mm or 28mm prime, throw in a cheap AF 50mm for the F4. You'd have compatibility with your lenses, and a more versatile camera to boot.
Then again, I never understood the Leica hype.
