If you are new and need help you can ask in the newbie corner. Most people are really helpful there even with the most trivial problem. Well you can also use it if you are more experienced, it is a nice place to get help and participate.
In other forums you are expected to have done some research first though, e.g. checked the wiki and maybe the bug tracker first and provide your relevant logs. That’s what might get you in this comics situation though.
If you can use containers always use containers as a rule of thumb. VMs are less efficient in almost every way and they add some unnecessary complexity.
For docker you basically only have to backup the persistent data. So in case of the docker setup you just have to backup the mounts and probably your compose file you are using. This probably also answers your third question already. Container files can be left alone and don’t need to be considered for backups as they should be stateless and can reside in their default location (/var/lib/docker/overlay2 or so by default).
Overall it is quite simple as you only really have to consider the mounts and the docker setup. The mounts you define and should be really obvious and the docker setup is just a few config files at most or just the compose file.
