I have a few questions for the general up-keep of my 2001 Tahoe.

Specs
-2001
-141k
-2WD
-5.3

I have a few questions, any general feedback is much appreciated.

1) Recommended Plugs/Plug Wires?
2) Recommended Brake Pads?
3) I'm looking for cross bars for my roof rack
4) Biggest tire you can run on stock ride height? 275 without scrubbing I believe?
5) I have a spot that faded on my dash, the beige/tan came off and it is black now. It is almost like a thin layer, I heard shoe polish could bring back the color. Any insight?
6) Any other info/tips/tricks/DIY would be greatly appreciated!


Thanks,
Merk
