Yes, one for each sender "class".

Almost, you need to remove the whitespace around the "=" sign in master.cf
option overrides (or use "-o { option = value }" in sufficiently recent
Postfix versions. http://www.postfix.org/master.5.html).

Anything you don't override applies to the custom transports also.
The only "exception" is concurrency settings, which are really
queue manager parameters not transport parameters, and have names
of the form "<transportname>_...", e.g. smtp_destination_concurrency_limit,
... those need to be set per-transport, or else you get e.g.
"default_destination_concurrency_limit", ...
