Start with that :
DO NOT MIX tagged and untagged VLAN on the SAME physical Interface ! So if you plan to have a "management" VLAN with no tagging on the PF : forget it unless it has a dédicated phys interface.
Use ONLY TAGGED Vlans for every VLAN attached to the same Phys interface!
Concerning the limiter, be carefull, keep in mind that limiter only applies to trafic LEAVING the (any) interface. Trafic coming in cannot be shaped. So if you flood your interface from the WAN, your limiter won't be involved : trafic leaving only.
Have a look to your Floating rules. The Wizard is sometimes tricky with rule creation. Have a check.
