Summon tinker you can only use at certain campfires.
Most of the skill you listed are reactives, meaning you need to be in Overpower stance (2-hand weapon) to use overwhelm and this skill is working after a parry response. Bash and shield are used after a block response (shield+one-hand weapon) meaning in shield stance.

Yes. Taunt and bash should 'light up' for a couple of seconds after your guardian successfully blocks an attack with their shield. ( an event you have no direct control over). Similarly, thrust 'lights up' just after a successful parry. Although you cannot control the events which make those skills available, you can 'bias' towards one or the other by your choice of stance. Guardian's defence makes block more likely whilst the other stance favours parrying.

Agree with other posters - most of these skills are reactive in nature. In fact, what I do is build my skill panel so that the skills always ready are the most accessible at the bottom row and go up from there. And I take into account what skills are needed to unlock other skills and stack them appropriately. Shield skills build - so I have them stacked according to how/when they open in the chain.
The summon tinker (which is awesome) is only available at campfires throughout middle earth. There are a lot more than there used to be and they will show up on your map. Super helpful and anyone you're fellowship-ing with can use their services as well.
It is definitely worth carefully reading all the tooltips on your new skills when you get them so you can build your skill panel appropriately - has helped me tremendously in 1) staying a live 2) fulfilling deeds 3) learning how to tank vs. running in OP soloing.
