The V6 is a pain in the a** even just to change the plugs. So many things to remove, so is better you change whatever you need to. As for plug cables not too sure, better bro. Danz comment on this.
Some car have different belts to run air con, alternator and so on and some just one belt runs all. If have not change before might as well change now since opening up

Other then those mentioned by bro. Danz, I think you need to change the internal oil seals too. Tensioner and bearings if have?

Usually if your pistons and rings are still in good condition they will do a top overhaul. Remove only the header de-carbonize, grind the valves, clean up and put back.
If need to change pistons and/or rings then is full overhaul
