1-Denter: If he has slacked out on work, did not keep his word and was a plain pain in the as5 to work with, he probably did a mediocre job, unless all material including paint and basecoat, etc was bought by you and you supervised the work yourself. I really hope the paint stays the same for a couple of years atleast. Personal experience; if the job is shitty, it'll look fine for a couple of months, maybe even 6 months, and then all the flaws would slowly start coming out and after a couple of years, it'll look like 5 year old paint.
2-Tyres: Writing from my experience, 195/55/15 are PERFECT for this car. Get a set and try them for a week.
3-Stagger: Again, staggered is when you put different width/diameter wheels in the frnt and back. This is usually done in RWD cars where traction is necessary. My car has staggered wheels with a more agressive offset at the back wheels. Cannot do much as these were installed by the previous owner, my rear tyres look woder than the fronts because of the offset. I have another pair or rims with me, will change to them soon.
If you mean stance, where the wheels have a little negative camber, then that comes automaticaly once you lower the car. The shorter spring makes the wheels go deeper into the wheel well, thus making the wheel sit at an angle and not flat on the ground. Further negative camber is achieved by using a camber kit, that can be arranged by our fellow pw'ers from LHR and Peshawar.
