Welcome to the forum, dstephns.
Your drivability should be just fine with 32" tires and that axle ratio (3.73). Having said that, there're a few things I think you could do to keep your JK more highway friendly.
For one thing, I don't know if I'd go with the stock Rubi tires. They're GY MT/R's - which give a harsher ride and don't do as well on the street as ATs (performance-wise and MPG-wise). Don't get me wrong, GY MT/R's are a great tough off road tire and I like 'em. I just see your concerns about "highway driving" and think a good AT tire (like the BFG AT or Pro-Comp AT) might be a better fit.
