Honestly your head must be reeling with all this stuff. Believe me at your level don't worry too much and don't get into it too far, you don't need ALL the info out there, most of it is not relevant for you even up to a 250 shot. A good N20 fuel supply, good connections, I step colder plugs perhaps and from the sound of it you must have a lot of cranking psi so watch the timing.
