A) Should that work?
2) IF that all works, do I still need the BOOST that was connected to my router when the Eero was setup?

2) No, at that point you could remove your BOOST. A long time ago, in a galaxy far, far away, you used to be required to have a BOOST to be in SonosNet. Due to some upgrades in the software, any Sonos device can fill in for the BOOST. Some of us still use the BOOST, since it's much cheaper than putting a regular Sonos speaker near my router, where I normally don't listen to music....but I could potentially get a longer ethernet cable, and wire one of my speakers, if I wanted.
