Why do you let the extra oxygen bleed out of a tank?
When "bleeding" an oxygen tank, you are releasing excess pressure stored in the regulator, not the tank itself. If the excess pressure remains, it can damage the regulator, and the guage needle can get stuck, giving an inaccurate reading of how much oxygen remains in the tank.

Does pressure have any effect on the oxygen level in the scuba tank?
I'm not quite sure that I understand your question .... Are you asking: a) does it effect the percentage of oxygen in the air in the scuba tank? -No. If you're diving compressed air, it's always 21% Oxygen, 79% Nitrogen, just like air (ignoring the 1% other). If you're diving Nitrox (where divers play with the oxygen levels, it still stays the same as it was when they filled their tanks) b) does it effect how many breaths worth of air you're going to get out of the tank? - Yes. The deeper you go, the quicker you will deplete the tank.
