Your head tube is 1", so you can't get a 1 1/8" fork, so your options are limited - same problem I ran into.
If you're really planning on moving to Atlanta and using this as your daily commuter, locking it up everywhere, I'd be hesitant to go with all carbon, but that's just me.
I wouldn't worry too much about using a shim on a carbon steerer though - just make sure you keep the torque in check. Also, I wouldn't use one of those death trap ships that Anya cut for Mark, as that had sharp edges, and will damage a carbon steerer. Thomson has some nice ones for $6 at Performance, or Lex could probably get you the same thing.l
