Regarding 3 (the blank screen issue when enabling a monitor): I can confirm that the issue happens when you're using Workspaces client 5.9.0.4129 (Windows client version) and no longer happens (even with Xdcv + Gnome) in 5.10.0.4196.
And, by checking the client release notes [1]:
"Resolved black screen issue when using multiple monitors with Ubuntu WorkSpaces"
