I need insight into user, power user, and dev bug reporting

i updated the README.txt regarding bug reporting.
i've been assuming that beta testers should report bugs to the beta topic corresponding to their version. i've been assuming that everyone else (power users and developers) should use Mantis directly.
is this correct? what methods do we want various people to use to report bugs? should i include more of Underflow’s “How to File a Bug Report via Google Code”?
