I'm 26yo, and I've a 14% portfolio for a lower risk option, and a 26% for a higher risk position. Should I change my higher risk option to the 36% portfolio instead? This would be for the long run?

It's always up to your risk tolerance but of course with higher risk exposure, the higher the return you will be expecting. As long as your risk tolerance is justifiable and you do not let emotions affect you during huge volatility and know how to dollar cost averaging or add in more position, you'd do fine over the long term.

That would depend on your risk appetite. If you are unsure, consider having multiple portfolios according to risk level (low, medium, and high) to mitigate the risk.
