Default bov hookup/wastegate

i am trying to put a kit together for my ls1. i am not sure how to hook a bov up to it though...i know there has to be a vacume line that connects to the intake isnt it? where would i get vacume from? i still have the stock ls1 intake...and when it blows off, does it have to return into the line or the atmosphere? i know that some cars wont run without it going back into the pipes becaus the mas is counting on that air..would the bov go infront of the mas or after??
Also, i have a 38mm wastegate. isnt there another peice that has that flap that releases the air? im not sure what i need to make the wastgate work???? im really getting confused...i would love to hear what everyone has to say.

For the BOV/BPV hookup I think the best place to tap into is the brake booster line.

I haven't a clue on wastegates, I'm a supercharger guy

You will hook the vaccum line into the brake booster line. I have an ATI kit and my bypass valve is blowing off into the atmosphere. I have my bypass valve before the mas.

The left connects to the back of the intake manifold, and the right connects to the brake booster.

You'll need something like this:
