I would replace the tensioner, spring and tensioner pulley when doing any timing belt job, first and foremost. You don't want a $50 dollar component failing and ruining a $4500 engine.

here is a repair info site that is quite good and and for a reasonable fee that has the info about the tensioner installation etc.
I would also replace the water pump, any idler pulley(s), the cam seals and crank seal, this is what a good Pro shop would do.
