I think you need to visit the VE thread. All and I mean every single one of your questions has been answered and in detail.

You will need a window switch to control VVL. If you have anything other than OEM pistons, you'll need to fly cut or replace the existing pistons. OEM pistons can be run with a thicker headgasket. I recommend a piston with valve reliefs if you plan to go that far.
