With regards to getting tickets for Garbage...
First of all make sure you are registered at tickets.com before tickets go on sale, it will make buying tickets easier. Do it now if you have time...
Secondly, if all else fails you'll be able to search on tickets.com for Garage and find the tickets that way. The event page will probably be available some time before 10am, you just wont be able to order tickets until 10am. There will more than likely be a "buy now" button with proper link on the 9:30 homepage today or tomorrow.
Thirdly, Special Needs, questions and requests should be posted in the FAQ Section. PMing moderators is not the best way to get answers, as some of us don't work at the club. Remember there are few clubs which have a FAQ area to post show questions in...
Hope this helps and good luck getting tickets...
