Lion does do a bit better at these things.
. Facebook has a tendency to change things around when the mouse moves over certain items, so I have found it better to have mouse cursor not follow voiceover cursor.
2. I would also suggest you make sure you are using the latest webkit and/or Google Chrome.
When these menus are properly defined, which I believe Facebooks are, then keyboard focus will move to the menu when you click on the entry button. At that point you should be able to use the arrow keys with out VO /quicknav to navigate the menu.
If chromevox on chrome works on your system I would highly recomend just using that for facebook.
If you really need help I could pull out my G4 systems and see what happens these days.
