I've used the Duplicolor Vinyl and Fabric spray (got it at AdvanceAuto) to restore the black carpet on my back shelf and it worked great. One can should be more than enough to do a shelf. If you are doing all your carpet, you may need 2 cans. The carpet will be very stiff after it dries, but brush it with a stiff bristle brush to soften it up and it will look/feel like new.

Works great on leatherette too. I used what was left in my last can to refinish my black hi-back office chair. Worked great.

For real leather (like seats or steering wheels) I would recommend a special leather paint/dye made by Meltonian. You can get it at shoe repair places (like Cobblers Bench at many malls). I refinished the steering wheel on my MR2 with it and the wheel looked better than new. If you've ever had shoes resoled and they looked like new when you got them back, that's the stuff they sprayed it with.
