For starters here are two great articles about bridges and VLANs in ROS:
On different bridge personalities
How to properly configure VLANs under ROS
I don’t think there are many tutorials for SwOS, it seems to be supposed to be self-descriptive.
And an advice: when trying to present configuration of your ROS device, use export command, it displays all configuration details in a pretty structured way (and does it recursively from current configuration tree point). It only fails to display dynamic entries, but those are rarely important (if they are, some fellow forum member will ask you to display those). The print command does grat job, but not in such a structured way … some people find it harder to read actually.
When I tried to understand the outputs you presented, I noticed one error you have (but you may have more): it seems you added vlan interfaces (created in /interface vlan) back to bidge as member ports (in /itnerface bridge port). This is wrong as hell. It’s likely you missed a few other things, so I suggest you to read through tutorials I linked and see if you can find your way around.
