In the general case, combustion efficiency will increase with increased air and better mixing (and, for a liquid fuel, potentially by better atomisation). Vapourising would be good too, I guess, but you'd have to do it in such a way that your fuel feed doesn't get coked up or "inverse bubbles" in it. The usual way of vapourising, by running the fuel through a feed line wrapped around the combustion chamber, has a tendency to coke up and clog with liquid fuels.
As for the question of "more thrust", then yes, gasoline will get you more thrust per kg of fuel, as it's more energy dense than propane. Diesel even more so. Propane is a damn sight easier to get going though.
If you want more thrust without worrying too much about the weight or efficiency, augmentors and water injection are your friends. The search function will elucidate.
electrolysis of water ... hydrogen and oxygen ... inject the gases into your fuel stream then it boosts the burn efficiency
No. No it doesn't.
