What state do you live in? If you live in a state that has yearly vehicle inspections then you might want to keep that in mind before you buy and O/R X pipe. If you do live in one of those states (like stupid Virginia) then you should get a catted X. That, or just hang on to your stock H pipe and reinstall in before you take your car to be inspected.

There should be an option to turn off your o2 sensors. Honestly, once you plug it in and search through the options, it's easy to find. I would tell you exactly but I don't have an SCT tuner. Good luck. You'll be happy with both the gear and the X Pipe, but the pipe is def cheaper.
