OK Let me put my 2 cents in IMO I NEVER put pencle beams on the bumper, They go on the roof. If it were me and I were traveling in pitch black like 90% of the outback I would have this set up.
5000k 70W hids in the lows- about 160, you want the 9006 bulb, I just bought these and love them.
4300k 35W hids in the fogs 880 is the bulb for these.(55W will melt the fog lights, headlights should be fine though)
I also have the toshiba HIRs in my high beams on my truck. 9011 in the highs, they are fantastic, I also have the 6 high mod done which lets all 6 run at the same time.
Now the offroad lights This is the exact set up im going for on my new truck. This is a pick up truck so I will be using a roll bar, but they make light bars for yukons that do the job just as well.
On the bumper a pair of these in FOG beam, its low to the ground and will really give you the wide beam.

then I would get the roof rack and mount 4 of these

This will be the EXACT set up I will be putting on my new truck. Other than my new truck has bi-xenon and will be 55W instead of 70 since they dont make a 70W bi xenon yet. But thats irrevilant to your truck since you have seperate lights for low and high. Expensive. But the light will be just awesome!
YOu can get this to mount the lights to the roof.

these are just 70W hids, no highbeams on no fogs on, Just the HIDS alone. the road is narrow, but you get an idea for the brightness atleast.
Now to see the difference, look at how much more light there is with the 70W
Here are 55w, just to show how wide 55W is, the 70W are even better.
just lows no fogs or highs.
