Moved to mk6 forum, since there is a lot of info here.
1. I don't know but winter tires help immensely in winter. The all seasons are OK but winter tires rubber and tread patterns work better on snow and ice. Even though traction control helps you get going, tires help you stop, especially in the winter.
You can go as low as 15" wheels. Check the hub centerbore - it should be 57.1mm which is the standard VW size. This is the thing in the middle of the wheel that the center cap covers.
Offset is how far the wheel sticks out. If they are too far in they'll hit the brake caliper. If they're too far out they will fling mud everywhere. In both cases it messes with the suspension geometry. Wheel width also determines how far the wheel sticks out.
See this calculator to play with offset numbers. For 7" wide wheel, 50mm of offset is OK on your car. Any more and the wheel will start to stick out. http://www.myturbodiesel.com/1000q/tire-wheel-gearing-calculator.htm
4. Look in the glove box, do you see a reset button? If so you have ABS TPMS. If your tire valve stems are stiff you have sensors.
