Sue,
I had exactly the same problems as you - and I did manage to solve them in the end (mostly) following the instruction listed by NBN here http://www.linuxquestions.org/questions/ar...004/01/3/122744
Those instructions aren't much help when it comes to answering all of the questions that fglrxconfig throws at you. Unfortunately I don't have those details on me at the moment. I'll try to get them to you in a day or so.
