The above is good advice.

If you plan to stay 17in for the wheels, 13in brakes are fine. You could even go 18in for wheels with 13in brakes. Performance wise, 13in brakes are more than enough for any street car.

I have no suggestion on front tire width aside from try to balance it with the rear if optimizing handling is a main focus. These old muscle cars tend to be front heavy already. You put a lot more grip in the rear by going with a much wider tire and you just end up pushing the front through turns. If you want looks and some better handling, you should be fine with 8 front and 11 rear. It's up to you and what the main purpose of the car is going to be.
