No; but it is inconvenient if you have to take into account the
current mode before knowing which method to use.  This can be taken
care of by using M-x calc-dispatch all the time, I suppose, but that's
not as nice as using M-#, especially when you might be doing a lot of
different things with Calc.

Yes.  Gnus definitely has precedence for M-#.  
Are there any conventions for global keybindings?  The key bindings
conventions section of the elisp manual don't mention any, and doesn't
even discuss M-... keys.

In the 2.02 manual, the installation procedure sets the keybinding.
