How long do you plan to keep the car? I wouldn't spend a bunch on it if you aren't keeping it long term.

Really you don't need to throw that much money at the suspension all at once. I would do 1.5" all around with BMR's springs, they are a great riding spring and the resulting rake is pretty minimal (I have those springs on my car and I like them a lot). New strut mounts are a must, get whatever good struts/shocks you like (Koni STR.T are good and not too expensive, LCA's for the rear, and an adjustable panhard bar. That will be a good base without draining your wallet, if you want to go further from there you can.

As for wheels, that probably depends on what tires you want. Anything from a 17 to a 20 will fit so you might decide what wheels you want, and see how much tires cost. I don't know off the top of my head if 10" wide wheels fit on the front but a 9" wide wheel will fit some pretty good tires.
