I may be wrong here, but if you're doing this:

 $ sudo echo 1 > /sys/kernel/debug/vga-switcheroo/switch

I've noticed similarly in the past that the echo command doesn't
actually run as root. I think it has something to do with echo being a
builtin. You could try either:

 $ sudo /bin/echo 1 > /sys/kernel/debug/vga-switcheroo/switch

or putting the echo into a script and then calling the script w/ sudo.

Unfortunately I don't have anything to offer on the other issues you
mention.
