I'm in the same boat. I have to stage my toons through dalaran making sure there is no more than two in at any given time.

I'm running windows 7 32 bit(going to try 64 bit this weekend)
4 gigs of ram
Q6600
Nvidia GTX260

Is there an easy to follow guide on symlinking? i'm not into programming and some of the disclaimers I've read make me a bit nervous.
