I am wondering how to climb steps. I am using a sphere to represent the players camera. How do I test using a sphere whether or not the sphere has collided with an object in front or to the sides? Thanks.

Take a look at this article...

Also, just have a general poke around here

yeah, i tried implementing the ellipsoid collision handling method, and here are the results. the only problem are "pulse jumps", but they can be easily removed by adding non-constant forces and friction.

here's how you can experience these "pulse jumps":
