lets do one at a time. the dizzy problem because I don't think you know how important this is. question did you change the oil pump? the usdm wiring have the crank sensor connected to the oil pump. if your answer is no then yes you wil have to run the 4 crank wires to the dizzy.

92si.... if iremember correctly you should already be wired for vtec already. check your harness and see if you have any plugs on your harness that has a cap covering it. it will be green. if not let me know.
