The dash bulbs are available in most auto stores, I had three not workign when I got my A4, was able to locate a set at Halfords
The dials are a lot easier to remove than they look. You have 2 philips screws right above thew steering wheel, it is covered bya flexible plastic panel that lifts up, then you can remove the fuse box cover (if you are RHD) and put your hand in behind the dials and push out. Just a matter of disconecting the plugs and drawing it out.
