Vinny,
I can see that by the choices you're going for a bang-4-the-$ setup.
The choices you've offered may be cost effective but I think they may leave you with an odd driving 4Runner. IMHO the OME springs in the rear will be appreciably stiffer than the very meek OE 4Runner front springs. I think the front will bottom too easily, feel soft and you'll have lots of brake dive with a "tight & right" rearend. For me it's about balance. I want balance and care less about soft, firm, whatever, a nice balance makes a vehicle nice to me.
I would think a Daystar 1.5 in the rear, Bilstien shocks all the way around (adjustable in front) and some Firestone airbags might be more cohesive setup. To do it really cheap (if your stock shocks are good) do a 2.5/1.5 Daystar and some airbags in the back.
OME 883's will work on the front with any OE or OE replacement shock, that might be an option too.
Or a set of FJC stuff with some Daystar spacers.
I just don't feel good about OME springs in the rear and OE 4Runner springs in the front.
That's just my unsolicited 2cents
