Ubershaders is a feature introduced after the 5.0 stable build, this post has more details on how they work: https://dolphin-emu.org/blog/2017/07/30/ubershaders/
Basically they stop games stuttering when new effects and such are drawn, and your GPU should be powerful enough for the performance impact to be minimal.
As for game optimizations... No need. Dolphin automatically changes it's settings in order to run games properly. The only exception to this that I'm aware of is to enable the Hyrule field speed hack in Twilight Princess, which isn't enabled by default since it causes the minimap to glitch a bit iirc.
