As mentioned, a set of camber bolts up front will get you some much needed negative camber and then just leaving the rear as is will get you close to where you want to be. spend the 200 bucks on bolts + alignment + entry fees.
I would recommend our RCE Tarmac 2s over KW V3 for autox. Our T2s are custom valved and custom sprung KW Clubsports with a lifetime warranty. We worked with KW extensively for a slightly more track oriented set-up (that still rides well). The V3s are great, but a little on the soft side. Just another option to look into when you get to that point.
Wheel/tire combo sounds good but will move you into STX. Which is fine if you're out to have fun and you can still do well locally.
