The way I've gotten around the problem with number two is to put code
like this in my .login:

	if ( "`tty`" == "/dev/console" ) then
	     workspace
	endif
	
This way only the "true" console window will start the workspace, and
you'll only get that window (in my experience) if you are actually at
the Iris screen.  The only thing that this requires is that you open a
console window, which most account configurations do by default
anyway.
