Well with a high flow header set up your going to have to rejet beacuse you are puting more air into the engine. So i would first get the Jet kit, then what you get next really doesnt matter. So when ever you do header or intake mods you have to re jet is what i am saying.

Same idea I have. You'll have to jet for the filter and exhaust, so the jet kit should be the 1st thing on the shopping list. I would probably get the exhaust after that since it gives more noticable gains than a filter.
