Here is where i would start: (if you have plenty of cash and want off-road performance & looks)
1. OME lift...I would not get OME shocks. Instead, i would get Bilstein shocks to go with OME springs. OME reputation exceed their quality when it comes to shocks (from what i hear). There are other lifts, but OME is probably the next best proven thing to Total Chaos custom works. Here is a search on OME lift:

2. Bilstein shocks (or whatever you like). If you off-road, then Bilsteins should do well. Good reputation and performance for life of vehicle (or so they claim).
3. Tires...BFG AT KO 32". Some people can fit 275-profile tire. I would just go with 265/70/17. You can also get Goodyear MT/R or BFG MT. There are other tires that are good but these are the big names. Any bigger tires may need re-gearing...so far, no gears are made aftermarket for the 4runner. (I think that Goodtimes is looking into them.)
4. Rock sliders with nerf bars. Hanna makes good one (see:
http://www.toyota-4runner.org/showthread.php?s=&threadid=12510). I am sure that there are others. Shrockworks makes one too (
http://www.toyota-4runner.org/showthread.php?s=&threadid=17104&highlight=shrockworks). Hanna apparently does not make one for 2006 4runner due to different mounting points on '06 models. Not sure on this one...so, i would call Hanna directly.
5. Transfer case skidplate:

6. Since you're lifting, then you may consider aftermarket bumpers. ARB makes good ones...but they are on backorder or something. Shrockworks makes one too.
7. If you get an aftermarket front bumper, then you want to consider winches. This is up to you...Warn makes good ones. There are other companies too...and all sorts of different types of winches.
For me, if i had a 4runner and wanted a lift, then i would do step 1-5. Bumpers & winches are still new to me...so i am not sure.
Hope this helps...and if anyone finds a mistake or want to add something, please do.
