you got it. Your config is very similar to something i setup for one of our VIPs. ( even the switch is the same)
yep its better to turn off the SSID if its going to be in a cabinet. reduce interference and RF footprint.
Also just make sure the decos can see each other (wirelessly) as well, as it needs to know RSSI, and neighbour AP to do the mesh transfer properly. (some just put it so far apart and complain that it disconnects)
tip: connect and power on 1 deco at a time. ! but have them all next to each other when you are configuring it. then place them where u want it.
Use an wifi analyser to check the signal before you connect the second and third unit makes it much easier.
