The wastegates only need pressure, no vacuum, sam goes for Boost controllers. The driver side charge pipe has a bung on it for this already.
You have to drill/Tapp the manifold for the BOV. It only needs vacuum.
And yes, the downpipe comes with an O2 bung already welded in.
EDIT:
I should mention that the kit comes with two drill bits, pilot and final size as well as a 1/8" NPT tap and a 1/4" x 1/8" NPT hose barb. So you don't need to go out and get any of this stuff.
