Ignore that guy...
Yes, both are possible. Place the triggerzone and set the main script to plrwithinzoneactivateifused.fpi. Set the IfUsed to the entity which has the 3rd person script. Place the 3rd person entity near the trigger zone, right click it, and set spawn at start to No. The second one is possible, but I think only possible through Project Blue/Project Green (Unless Fenix Mod now has camera controls).
