Lineage and Devolutionary trait question.

Hi, So excited to have my rule books and get stuck in to creating my first faction. i just have a couple of questions about Lineage traits and Devolutionary Traits. I think I just need reassurance that I have it straight in my mind.

Firstly with the lineage traits. If I select 1st lvl traits from 2 lineages as faction traits will all my classes gain those traits, even if I give a class a new bloodline? For example if I select Troglodyte as a faction bloodline and then select Saurian cunning as a lineage trait, does that mean that all my classes get the increase Command 1 effect of the Saurian trait? And following on from this if I were to give a class a new bloodline trait would it still retain any Troglodyte lineage traits from the faction traits? If so do they all stack?

Secondly with regards to the Devolutionary traits. I see that they do not stack with traits outside their Devolutionary branch, presumably this means that the lineage faction traits still apply to them, they just wont "stack" with Devolutionary Traits? So, using the example from my previous question, if I had a class which took the Thunder Lizard trait as a class trait would the Saurian Cunning trait still apply to them? Also, if I had taken the Troglodyte bloodline as a faction bloodline then my thunder lizard would presumably gain the increase Strength 1 that comes with that, but then if I took the Primal strength Devolutionary trait as a class trait am I right in thinking that I would actually have increase strength 2 because the Devolutionary trait and the bloodline trait wont stack, but the class trait takes priority?

Sorry there is a lot of questions there. I want to make sure that I have it right before I start to build a second faction. I am desperate to have a game and can't wait until I have other people to play with lol
