Being a road car as well is always a compromise as you have to factor in tyre wear.
What suspension are you on?
When I used to track my daily I found a good benefit from fitting new wishbones, track rod ends, roll bar bushes, top mounts and drop links. This helped stiffen the car back up like new and didn't cost a huge amount, don't buy cheap stuff though, I bought Delphi parts which are OE quality.
Rear adjustable anti roll bar makes a good difference, uprated the front roll bar to the mk5 twin top one as it's thicker.
Some turbo front brakes, braided lines and yellowstuff pads as a minimum really.
Settings wise seeing as it's a road car I'd start off at:
Front: -2 to -2.5 degrees camber and 0 to 1mm toe out.
Rear: it's fixed but can be adjusted with camber shims, try and adjust it to run 0.5mm toe in to 0mm and -2 degrees camber.
If your pockets are deep, get some gaz gold black edition or AST's and 500lb front springs and 400-450lb rears (dampers on soft still feel nice on the road)
Solid subframe mounts are worth while, as is the rose jointed drop links, spherical bearing wishbones and rear beam bush from RnD motorsport.
