Of the above choices, I would choose the flow matched set.

No, to answer your question, you do not have to have the hot wire kit, but you pretty much SHOULD get it. The factory pump wiring sucks ***, and when you install an amp hungry pump and try to run it off the already lame factory harness you are just asking for trouble. Get the hotwire kit, it is good insurance for sure, and it is very well made.

as far as injectors, I second the flow matched ones.

Any of the injectors you list above will work on your car. You will have to retune the PCM for the larger injectors to function correctly.

A little, but mainly for reliability. Flow matched injectors ensure you are getting the same fueling to all cylinders.
