Careful with Procomp lift kits, they use a very stiff coil! The difference between 5100's and stock coils and an aftermarket coil is the preload. 5100's give you lift by preloading the stock coil, lift coils are longer to begin with so they don't require the preload to give you lift.
With suspension lifts on a 2nd Gen that near 3", you might find that you'll end up needing new upper control arms to get a decent alignment. 5100's at 2.5 give you about 2.5" of lift and there are many members with that amount of lift that are still using stock control arms. At 3", you will be hard pressed to get a decent alignment. Aftermarket UCA's are in the upper $300's. That was one of the reasons I mentioned spindle lifts. They retain the stock suspension geometry so new control arms are not needed, stock ride is maintained and lift is achieved.
If you do go with a full coilover kit, check out the Old Man Emu kit from either Toytec
or Downsouth Motorsports
(make sure you mention you found them through TW if you order through them). OME has a lower spring rate so it'll be closer to a stock ride. OME coils can be mounted on Bilstein 5100's or OME Nitrocharger shocks.
If you're trying to get to 3" of lift, I'd go OME over the Eibach kit. OME 885 coils with the short top plates get you to 3" without preloading the coils. Eibachs are a stiffer coil to begin with and require you to preload them to get the same lift.
