well a nice tip i have used over the years is if you use the fatory lug nuts (the ones with the rib on them ) you can use any chrome center cap you want im including pics of my aftermarket wheels with my factory 96 centers but they make a few different styles to choose from.
the back is factory like 3" higher and the reason they do it like that is so when your towing a trailer it will sag and make it level. the back you can lift up to 4 inch with blocks and there easy to get airbagit.com has lift blocks for like $36 thats everything you will need for the back. the other thing i can recommend for the back is the add a leaf. when i did this to mine i added a leaf out of a older chevy truck i got 3.5" lift and a great ride
