Answer to both is yes. Though how is not known to me at this point.

Squid is capable of setting a mixture of outbound QoS flags. Information
about using those with iptables etc seems to be fine. But when people
throw TC into the mix with newer Squid something appears in the routing
behavior that we have no documented info about.

I am also seeking a TC expert to help several users already needing to
use it with TPROXYv4 and/or WCCP setups.
