Any auto paint store can get you pinstripe tape in a variety of types and colors. The rolls are big enough you can make mistakes and peel off the stuff as needed. That's what body shops do, unless they're using painted striping.
Rolls of tape aren't that expensive and they should be able to give you some application tips. It's a lot of fun to play with pinstriping tape. Get a roll and have a go at it.
Wheels will be a bit tougher than bodywork, you may need to either get a custom kit or play around a lot.
