I would switch the drivers to GE Enbrighten Z-Wave Smart Switch and GE Enbrighten Z-Wave Smart Dimmer, be sure to hit configure after changing the driver.
As far as other switches I have a couple Zooz Zen71s that work fine with a regular switch instead of an addon switch.
Zen77 would work for those dimmers in 3 and 4 way setups
