The manual should identify items that require/recommend replacement; either via Maintenance Schedule (like the timing belt) or in the course of service. For example...

Bearing Retainer - Product ID: YS4Z-3N324-AA (referred to as 'the halfshaft bracket' in the service manual)
Interestingly, the service manual makes no mention of discarding either tensioner, at least not where I'm looking (2015, Timing Belt (Removal and Installation, 303-01 Engine - 1.6L EcoBoost)). The accessory belt tensioner is $85 on Tasca ($137 MSRP) and looks pretty beefy, which is why I'm questioning whether it's worth the money to replace.
Your list is good. I also had the thermostat and housing changed while everything was apart. I had my dealership do it so I'm covered under warranty for their work. No complaints so far. The mechanic has over 28yrs of engine building under his belt!
Is the thermostat accessible while doing a timing belt?
Because I understand that it's very difficult and time consuming to get to, so when I have my timing belt done next summer I may consider having my thermostat changed also, thanks.

It took a good amount of effort to get to this point so I can definitely see why it should be replaced at the same time as the timing belt (and water pump).
I've come this far, so I might as well give it the works!
