how much high way driving you do? If a lot, keep the gears you have in it now. If lots of city driving, 4.10s are your friend. Mine was my dd for long time with 35s on it. I did lots of high way driving, so I left it with the 3.55 gears in it.

4.56's. puts you close to stock, IMO its ideal.

4.56's with 33's at 65MPH will put you close to 2113 RPM
4.10's with 33's at 65MPH will put you close to 1899 RPM
3.55's with 33's at 65MPH will put you close to 1645 RPM

3.55's with 28.3" tires (225-75-15r) at 65MPH is about 1960 RPM.

300 rpm doesn't sound like much, but can make a big difference for towing/cruising. I like having passing power and off the line ease. thats why will be running 4.56's.
