Pulling the trigger on an Icon stage 4 set-up

Before doing this, I am trying to get some questions answered so i can do it all at once. Maybe some of you have done the same or read it somewhere. @icon_rep can chime in too hopefully.

So I am sitting 100% stock right now but hope to get the stage 4 set up going here soon. My goal is to have it installed due to lack of space and time plus some ease of mind. I am hoping I can get into Demerol Offload for the install and support Riverside.

I plan on getting some 16" @SCSPerformance wheels and tossing the tallest tires I can on them without having to worry about too much rubbing. It will be fairly rare that I am fully compressed during my type of driving and off-roading mainly because it is also my daily driver. So I am thinking 285 75 16 as recommended by Icon. Thoughts? Do I need to worry about any backspacing with the SCS wheels? They seem pretty standard and I see their wheels on tons of tacomas anyways.

I hope to get it all done in the same day, any specifics for alignment right after?

Also, I have pans for @Pelfreybilt shortly after and was curious if the 700# springs were sufficient and how you go about adding those in the ordering process?

Thanks for the answers ahead of time and I would appreciate any photos of similar set ups/tire sizes.
