Will I need to reconfigure all my devices over to the new Wi-Fi one by one?
If you set your Wi-Fi network name and password to the same as it is now then no.
Can I have two wired H2D's with 3 Points in my home?
I assume you mean two hardwired routers/points and 3 non-hardwired routers/points. Strictly speaking yes, but we do not recommend doing that. These kinds of setups are much more likely to cause problems that are very hard to diagnose. The primary one being that if one of your non-hardwired Wifi points can establish even a weak connection back to your primary Wifi point it will do that, over connecting to an intermediate closer Wifi point, because it prefers the least hops to get back to the primary Wifi point. This is also the reason Google recommends placing your primary Wifi point as close as possible to the centre of your home. The best advice I can give you is to do one or the other, not both. Either build a pure mesh topology (i.e. don't hardwire any of the points via ethernet) and follow Google's placement guidelines . Or, build a full ethernet backhaul setup where all your Wi-Fi points are hardwired.
Where to place your Wifi devices - Google Nest Help
Both routers are wired to the main router from Verizon in the basement.
Only one of your Nest routers/points should be hardwired to your Verizon router, this is your primary Nest Wifi router. All your other Nest routers/points need to be behind your primary Nest Wifi router. If you don't do this, your primary Nest Wifi router won't be able to control your other routers/points properly.
Hardwire Nest Wifi Pro, Nest Wifi, or Google Wifi with Ethernet - Google Nest Help
Finally, please be aware Nest Wifi Pro is only compatible with Nest Wifi Pro. Nest Wifi Pro (Wi-Fi 6E) can't be combined with Nest Wifi routers or points or Google Wifi points (Wi-Fi 5) in a mesh network.

Hope this helps!
