I don't use ogg (yet) but those switches look OK. View the man page for oggenc (type man oggenc
in a shell) to verify the switches yourself.
I am fond of a script called dekagen
to rip CD's quickly and efficiently, but I use Grip a lot too. It all depends on what mood I'm in.
Dekagen might just be a tad easier to use than Grip even though it doesn't come with a point-and-click interface.
