I checked out those TAG bumpers and they look pretty cool. The WK front bumpers they make are ugly in my opinion but the XK ones look pretty awesome. I personally prefer the SA rear bumper but the TAG one still looks very cool.
As long as the Rubicon wheels are 2007+ (JK Wrangler) they should fit with 1" spacers. Check for those pockets on the inside of the wheel. Worst case, you have to trim the stock lugs. If you're going with 1" spacers, I'd go with Bora. They're a little bit pricey, but I think they're worth it. Spidertraxx and RC don't make 1" spacers as far as I know.
