There are Targeting options in the character config. you want to make sure targeting non party-PCs is checked. There are two different targeting schemes, one is with your weapon sheathed, the other drawn. I have it to where I can target everything but minions and party members when it is sheathed. when it is drawn i have it target all enemies, aggro enemies, and other-PCs. this makes it so you can target NPCs and objects when questing but still be able to target other people in the open world. Then when your weapon is drawn you can only target enemies and non party-PCs with left/right on the D-Pad. I don't have party members on this targeting because you can just use Up/Down to get to them easily.
There may be others that have better setups, and there are options for different targeting modes if you hold L1+ a button or something, but I Haven't messed with them. I found that this setup works pretty well in the overworld and instances. I had to turn off object/npcs with weapon drawn b/c I would target objects in dungeons and not be able to tank properly. Plus you don't want to be targeting party members if you're looking to throw some quick Aeros out on the mobs.
