Also what's the deal with twin spark in regard to Turbo? My understanding of it is that it helps with higher compression engines, and since Turbo, by their nature are lower... I shouldn't need to go twin spark anymore.

John Dougherty a.k.a "camgrinder" from DRC cams, can grind the stock 3.2's to the popular and sought after 964 grinds up to 993SS (super sport) if you beg him.

If you are running flat-top pistons, twin-plugging is not as needed as the general consensus goes, but is said to be safer and makes a little more power. If you are staying at lower boost levels, probably not all that worth it. But, "cgarr" here can do the twin-plugging to your heads for a pretty reasonable price if you must.
