Mlynar and SA are great for farming when starting out but eventually you are gonna be doing all your farming with tools you make.
Defenders are good for picking up stuff at first but once again you will eventually use tools for this, they will fall back to their usual defending role.

You are spot on for that, and she is great moral suppors since she is super cute.

Good for plugging holes in your build and yeah, hunting animals.

Build your base eventually but its not something you really need to prioritize early as long as you are intercepting raids/destroying raid spawnpoints.
I would also recommend bringing someone like fiametta and building chokepoints around her infinite duration skill or something of the like.
