There are a number of VW specific vendors that will sell you a front end "refresh kit"; you might look at those... see if they save you some money. One thing I would do is check the bushings in the rear axle beam bushings and front control arm bushings. The front bushings is a very common fail point; I would go with TT/R32 heavy duty rubber bushings and possibly aftermarket bushings from Black Forest Industries or just the stock rubber ones. The BFI ones I installed; were supposed be "graphite impregnated" but I am experiencing squeaking from them, so... the rubber ones probably don't squeak but probably won't last as long.
Examples; the tt/r32 has full rubber and no air gaps that the original ones did, they will last longer and firm up the performance, feel of the front end. Most people recommmend the tt/r32 bushings, stock rubber or better aftermarket but to stay away from the straight poly bushings, because they are noisy.

BFI bushings; seem a little squeaky to me, unless something else is making the noise!

They probably will last forever; however!

The rear axle beam bushings; wear out as well. Mine, the rubber is cracked and in bad cases, the assembly gets loose. For the rear; I think you can get heavier duty ones, possibly from the R32 and the poly are not recommended, as they wear quickly, are noisy and apparently, bind.

When it comes to looking at a number of companies selling suspension kits; it is easy to look up at tire rack.

Replacing the strut mounts and bearings are probably a good idea and would eliminate any wear and noises.

For the camber issues; I have been told you can buy "shims", to try to help with the issues, give your alignment shop more adjustment capability. I haven't bought any or tried them but my car does suffer from cupped tires in the rear; so, maybe they would help.
