Rancho Set Up

I have been researching for almost a year now and should have the money for everything i am looking. I am looking at the rancho 4'' lift kit with 35'' Toyo MT's with 18 inch Diamo 17 Karat rims. Ride quality is rather important with me and i will not be doing much off roading and only occasional light towing. I am wondering if the add-a-leaf kit will be a good match for the rear end and if the height will work over the blocks. Shock wise i am thinking of going with the rancho 9000 remote resi's all the way around. What are the opinions on going with duels upfront. I know they look alot better(in my oppinion) but just wondering if they will help with much else. Beyond that i was also curious with maby a steering stabilizer. I dont even know if they are needed much with these ifs systems as i havent seen many but just wondering on options there. I plan on going high quality without cutting too many corners as this will end the mods on my truck. However i am still trying not to go too overboard on everything.

All comments, opinions, suggestions, criticism, will be greatfully accepted. Very curious on whether people think this tire rim combo will work. I would like to keep the trimming down to an absolute minimum. All installations wil be done proffesionaly. Thank you,
