Actually looks pretty simple, just drop the lowest part of the dash where the heated seat buttons are. From the diagram it appears it is only 4 screws to pull the lower panel after you remove the access covers, see page 7 of the PDF.
Just be aware that the buying a complete Torx driver set will be FAR cheaper than going to the dealer.
The Aux jack popping out is a COMMON problem. My car is a 2003 and did not have an Aux jack so I do not know how they are mounted, my guess is you will need to epoxy or come up with a better solution that VW originally had to hold the jack in place.
