I bought the 2 gallon kit from Monstaliner for $260 because I plan on doing the bed of that Tacoma in the background... that's my new work truck 
1 gallon black is about $130 ($150 if you buy the kit with roller and pan). There was plenty left over even after I did both bumpers and skid plates. I also did my boat deck with tan Monstaliner and it turned out really nice! The tintable one is a little more, but they have a ton of colors if you were trying to color match.

After:
The 16x8 has 4 inches of backspacing, so that would probably work too...

As for rims, with 15x8 rims and 35x12.5 tires, nothing sticks out past the fender flares on my SR so you could go a bit wider if you wanted. My backspacing is 3.75 or something like that.
