If I understand you correctly, watch the “changing first/third person tutorial” and then simply remove the keybind for switching cameras. That should lock the camera to the mode you want.
Your maps probably aren’t cooked. Watch the “add custom map to UI” tutorial, even if you don’t have any custom maps. That might solve your all your problems.
So… Dedicated Server support is a bit weird, in that, Generic Shooter already supports it but it needs to be wrapped in a code project and then compiled for Windows Dedicated Server. What is missing though is an easy to use documentation guide and if you’re using dedicated servers, you most likely want some advanced features that simply don’t exist in BP/Built in engine, such as…

Being able to set your server, game, and map name, and have it officially registered with Steam servers, as currently you have to deal with “can people see my server or not? why?”. I have wrote a C++ Plugin that solves that, but its not feature complete yet. There are things I want to add such as adding player avatar fetching and other forms of advanced server management. I’d like to get this plugin on the marketplace but we’ll see what happens. In the mean time though, I wouldn’t stop anything your building in anticipation for the update. It could be awhile and there are a lot of things to sort out. The next update will probably support 4.9 only as well, as there are some things in 4.9 I want to use.
You could do camera zoom by messing with the desired fov in BP_PlayerCameraManager, but 360 panning? Sorry, can’t help you there.
