First of all, congrats on your purchase of one absolutely gorgeous car!
I'd be concerned about putting forced induction on top of that 11.5:1 compression ratio without at least changing the head, pistons, or the whole engine altogether for something with a lower CR. Without changing the engine, you're pretty much limited to minor external bolt-ons (exhaust, intake, etc.) that might be good for a couple HP at the most, but would make it SOUND a lot better. I believe Dinan makes an upgraded chip for your ECU that, knowing Dinan, should be worth another ~20 HP.
As far as suspension goes, half an inch lower with stiffer springs and a good set of Bilstein Sport or HD struts will make an appreciable difference in handling quality.
Side note: the stock wheels look far better than those Volks, imo.
