As long as your broker hardware is adequate that should be fine. Brokers
on commodity hardware should easily be able to manage tens of thousands
of queues.

I would look at the topic routing tutorial:

If you want to be able to route based on different components of the
message type then use topics. This option gives you the most flexibility
and is probably most appropriate in your case.

That depends on your application, but it typical to keep them separate.
