Benjamin I would gladly help you out but I just can not picture what you are describing.
Do you have one service panel with two sub panels or did you have three service panels?
Pictures of the open panels would help.
2/0 copper can be used for a 200 amp service but it can also be used on a 100 amp service.
The standard answer would be that the service size is rated the same as the lowest rated piece of equipment between the Service panel and the utility.
One set of 200 amp conductors feed a 200 amp meter socket, from there one set of 200 amp conductors feed a 200 amp panel with 150 main breaker.
That would be a 150 amp service.
But you could have a service like this;
Two sets of 200 amp conductors feeding a 400 amp meter socket, from there two sets of 200 amp conductors each feeding 200 amp service panels.
In that example you would have two 200 amp service panels for a total service size of 400 amps.
