Enhance existing jQuery script snippit to include an array of values from a mysql database & limit a selection of clickable items

I have an already existing script (based on the tutorial at [login to view URL] but slightly modified already) that allows the user to reserve (virtual) seats. The seats are picked via a little jQuery script styled liked your typical airline reservation graphic. Upon selection the customer is sent to a simple booking page and name and selected seat number are entered into a mysql Database. On the next visit of the page the booked seat will be grayed out. What I need done (probably only requires a few lines of code and 20 minutes of work but I'm utterly stuck so looking for someone else to do it!) - get the array of seat numbers that are booked and put them into a jQuery variable. The variable exists and is set up in the script to gray out the seats but the values are currently just entered by hand - limit the selected seats to one. right now the user can happily click and select however many seats they want Deadline: even though this is a private, non commercial "fun project" - looking for someone who can finish this within 3 days.
