Have you has a read through of the following PDF from the D2 Tech Dump thread? It covers all the suspension parts, but not exactly in the way you mention i.e. a complete rebuild as opposed to broken down into individual parts.

The timing belt is a DIY job, so long as you have the correct locking gear and the patience to check your work. I did my first complete change last April (2023), and now have to do another change because the belt is moving a couple of mm. Despite going for 'quality' brand names, unfortunately a lot are now being made in China, so you can't even go by brand name, unless you know where they were made (see photo below).
BTW I come from an IT background and never worked on any car until I bought the A8. Like yourself, money is tight, and no one here in NI will even look at the car. One exception... and that didn't go well.
