your offense rating indicates your raw hit chance %; minus enemy defense rating is your actual hit chance.
STR and DEX just increase offense rating. (DEX also increases defense rating)

throughout the game there is really one enemy that's extremely difficult to hit (no matter how high your STR or DEX is it seems), and so, yes, getting more APs would be much more beneficial in combat.
