My opinion (based off my suspension):
Find a coil, in the 300 ppi rate and the correct length, that would net you around two inches of lift. There will be some research needed to figure out the exact length coil you will need. I run a Deaver super flex coil that is rated as such. I moved my stock coil bucket up one inch and had to cut about 3 - 3 1/2" inches off the coils and massaged them into the stock coil buckets to make them work. I retained them with a exhaust ubolt kit.
Get a longer shock. I am running a 14" travel shock using the f250 shock tower mod.
Extend your brake lines using the brakelines off of a 2000 f250 superduty with rear abs and manual locking hubs. (sorry dont have the part number. I'm sure you could find it on this site or someone will post it for you or tell your parts guy what your looking for if he has any idea what he's doing he should be able to find it for you.)
Get a dropped pitman arm. I believe the part number for this is FA400. I truly believe the FA400 would be perfect for the 2" lift. Most sites will tell you this (FA400) dropped pitman arm is for use with a 6" lift, however, I ran it on my 5.5" lift and it was not long enough. I ended up buying the longer pitman arm FA600, which is supposed to be for a 6 - 8" lift and is barely long enough for my 5.5" lift.
Get longer radius arms. Not necessary with a two inch lift, but for better flex any new, used, Duff, Skyjacker or make your own radius arms would make this suspension come alive.
This should get you a nice flexy smooth ride on the front.
For the rear, there are a few things you could do. AAL: add a leafs (the way I went but rode stiff), Warrior shackles (would probably ride the same as stock, just adding down force on tired springs) or I believe some on this forum add a f150 main leaf to their exsisting leaf packs and cut off the eyes of the explorer main leaf, making the f150 main leaf the new main leaf in the pack. I have not done this mod but heard it can net about 1.5 inches of lift and flexes well ooorrrrr buy a custom leaf pack.
I ran 31's with a two inch lift but could have definitely ran 33x10.5's with that setup if I trimmed the front fenders or got glass fenders.
Ditch any lower body moldings, the factory style auto hubs and f/r sway bars. Add a locker: front, if you have a rear l/s. Rear, if you dont have a rear l/s), jeep hubs, c-clip eliminator.
If you have the extra funds and get a good deal, getting the radius arms or making them and a locker would set you up to have a lot of fun. A winch and sliders and you would have a extremely capable explorer.
I priced out just the suspension stuff and you could have the lift you want with all the above listed parts for the front and rear for about $500, minus the radius arms.
So, there you have it. My opinion.
