Dave wheels are a personal taste thing, you will need to deiced just what you like but in my opinion, I would use 15" wheels but if you feel the need to go larger dont go over 17".
that color is great and should look beautiful on that shape car.
I wouldn't get to carried away with graphics as that color stands out as is. maybe something subtle like pinstripes.

I think the fatman frontend is a good way to go and the 8 3/4 rear works out good too.
the 5.7 hemi and 5 speed auto will make the car a great driver friendly car.
I would see if you can get some newer rear springs for the rear, something wider than the 1 3/4" stock ones.
maybe something from a mini truck(thats what I use) Ron....
