First to work with vlans best to read this excellent article with examples.

One bridge.
All subnets get vlans (dont use bridge for dhcp is my recommendation, keeps it simple apples to apples)
Do not use multiple bridge.
Simply setup/identify the vlans to the bridge interface
ALL vlans require IP address, IP POOl, dhp-server dhcp-server network.
Setup interface bridge ports
Setup interface bridge vlans
Almost done.
Do use the reference, and by the way their management vlan 99
can be your homevlan or trusted vlan, one doesnt need necessarily a separate management vlan and rule of thumb is the vlan that the admin uses all the time.
All smart devices attached tot he router such as switches should get their IP from this vlan subnet etc…
As for external switches I will have a look later once the MT config is fixed, no point otherwise.
Typically though all trunk ports on the switch keep their native VLAN1, and access ports lose their native vlan1 which is replaced by the PVID of the vlan passing data to dumb devices.
More on that later.
