Ive already got head gaskets, and an oil pickup. I need to get intake mani gaskets. Any other gaskets I will need?

Also, where should I get an o-ring kit? the dealer/subarugenuineparts?
Can you define "far too agressive" ? Was the piston to wall clearance low ?

Honestly I wouldn't consider going any further than 100mm if you plan on making more power. The more you take out of the bore, the weaker the liners will be.
