Tried boiling a brew on the weekend. Have always just added ingredients to the carboy with hot water. Boiling is so much more interesting! Anyway...

Can you boil a brew too vigorously? Should you see bubbles rising - how many at once? Is it more of a simmer? What signs do you look for to indicate the correct boiling 'pace'?
A good rolling boil is generally all you need. I doubt that over-vigourous boiling would oxidise your brew, because boiling actually drives out the oxygen, as far as I know.

You should see the boil "rolling" over and over. Its fairly vigourous. More than just bubbles or simmering anyway. You want it constantly turning the hops through the liquid.
