The Ground Control system is a decent way to go, but the "trend" in suspension tuning (if you can call it a trend) is to ditch the custom rate GC/Skunk2 sleeves for "true" coilovers (Tein SS, Zeal B6, etc.) If you're on a budget, the GC + Koni yellows (around $800 total) are a tried and true setup that should be more than enough for your needs.
I have heard mixed reviews about the Tokico's which is why I'm recommending you go with the pricier Koni's.
