its safe to assume that you are looking for about 2-3" of lift with that OME combo, and speaking from experience, unless your rig is loaded down with a lot of extra weight, I wouldn't go the OME route...I had 880/906 combo with the "comfort" 60073 shocks and it was anything but comfort! in fact it was annoying and bone jarring to the point I had to switch out to my current setup...but keep in mind I also didn't have any extra weight though so that is a huge factor...
I reccomend looking at Absaloms lift ideas here

if you're goal is 2-3" of lift get 99 talls all the way around with bilstein 4runner shocks or OEM shocks all around and 1/2-1" body lift, OR you could do all suspension lift no body lift and get TRD Tundra front coils or even Toytec 3" coils in the front, and in the rear look at some used LC 7 wrap coils or superflex coils paired with OEM LC shocks or Bilstein 5100 shocks...
keep in mind if you go more than 2" of lift your stock tires will look small (trust me i had a 3"-4" lift with 265/75s and it irked me!
and always keep in mind any existing issues you may have with other suspension components, adding a lift will likely only exacerbate those issues...if youre going over 2" of lift you should get a differential drop and start to keep a close eye on the CVs and LBJs, but dont watch your MPG cause you will only get upset!
