Which underdrives would you recommend for my Xr8 ute? the 10% or 25%. I have full exhaust, CAI (unfortunlately an SS inductions one, but will be 'upgrading' soon) and that's it.

well if you are going to the effort of putting them on i would put 25% ones as the 10% does not do much ...
If your car is manual you need to do oil pump gears aswell.. I would get the car custom tuned if you are only looking at doing a few mods as the car will be totally different and we can mail out a tune to you ...

is it better to do the whole pump with the billet gears or is it just as good to replace the gears only?

If you worried about the pump speed, theres a PB kit that replaces the pump pully wheel which lifts the speed of the pump back to the factory speed.
