Have a pic of your 4Runner?
E-locker?
If Kurt is not available I would contact Steve at Sonoransteel.com he is the Kurt of 3rd gens.
Toyteclifts.com is an OK resource for 3rd gens as is Daystar.
The rear brake line will need to be replaced with a longer unit. There is no proportioning valve as it is a 4Runner. Front brake lines are long enough for use with a standard kit.
The diff-drop IS necessary for CV longevity and the resulting loss in clearance is hardly noticeable since the factory skid covers it.
The use of longer front springs will require a spring compressor.
For your time constraints I think this is your best bet:

In all honesty I would remove the running boards, mud flaps and maybe the rear hitch and take it easy. Save for a permanent lift via Kurt/OME or SonoranSteel.com
Removing the front sway bar is a mistake.
If you decide to lift before the trip do the shop or yourself a favor and get out there NOW with some WD-40, PB, LPS, witch-piss, whatever and spray all those old fasteners down.
