I have been down the road you are travelling on now. I always start one wow client first from the main folder just to see if there are going to be any patches/brief updates/whatever. Never start 5 wows without seeing 1 wow first.
Sorry you had to go through all this pain. 12 hours of DL and reconfiguring your toons... Back up every Monday night. At least with a back up you can start over in 30 min or less.
