Just wondering if someone could explain to me if I need to take out an insert in the exhaust? Also, high altitude jetting numbers? Main/Pilot?

Thanks

YES take it out, there is a small insert inside the stock tailpipe, it will free her up, and you should get the AIS removal kit and it will really uncork your bike. You can also go further and buy a Promoto tip and maybe remove one baffle from the stock muffler to really free her up..... Stick thread above talks all about it.
