get some microfiber towels to wash and dry the car. I got a pack of those turtle wax micro fiber towels. The ones that wallmart sell are comparable in quality. Small but they do the work. They dont scratch yor paint like terry towell would. i use 2 for driying, one for washing.
You saw my car at the six flags meet (only black wrx there). I would also hold on the waxing, at least untill you get something good to apply, like Klasse AIO and Klasse SG. Not wax but acrylic protection. Best stuff Ive used. If you drive to my house I can do your car
but im too far away.
