There were no clear instructions on how to install the basic kit, but only the stage 2 kit but there are somethings that are not in the instructions since there's different parts for a different kit. There is a adapter that fits into the back of the fuel rail that looks like this:

Do I put this adapter on the driver side or the passenger side?

If it is the passenger side, there is this part that I'm confused about:
there is 2 rubber hoses that go into the dampener, do i completely remove this? What do i do with these hoses?

I have seen ppl run without putting in the vacuum or boost line, is this important?

Here's what happened, i start up the car and it starts up really quick
and it stays on and the fuel pressure reads at around 48 psi..I turn
it off and start it back up again to make sure there's nothing wrong,
nothing this time....next time i start it up it starts to bog and shut
down, now i can start it up at all. I'm thinking b/c the fuel line
going from the rail to the fuel regulator is short and it starts to
crimp the line, so i unmounted the fuel regulator and straighten out
the line but it still wont start up.
During the install I didn't need to take off the intake manifold off
since i could get the adapter in pretty easily from the back, soo that
rules out any lines that were missed when reinstalling the plenum.

"I have seen ppl run without putting in the vacuum or boost line, is this important?"
After reading the blurb at AAM, I'd say you pretty much defeat the purpose of the system by not connecting a line to the pressure regulator. Connecting the regulator to the intake allows it to adjust the system pressure as the intake manifold pressure changes. That's probably more important for FI cars than NA, though.
