Just use a std motor factors, I've used QH stuff for over 20 years without problems, but the new DAYCO belt/tensioner kits are good, use these myself.
The rst is a very easy lump to work on, tensioner is easy as well, just has a wheel on a sliding affair with slotted ends, so tension up tighten bolts either side.
Don't forget fuel filter.
I would use Mahle fuel filter, if you can get it, and a known make oil filter, ford are certainly nothing to be proud off oil filter wise, had more trouble with genuine ford filters than all the others put together.
