You should always make the near plane value as far as you can. I use 0.1f personally because nothing much gets close to my camera but the further from zero the better.

Here's why.

Same with the far; in general make it as near as you can.

As the article states, don't try to "cover all ground" by going from 0.00000001 to 1000000000. Instead try to analyze your needs and split your scene into "near", "middle", and "far" (or whatever) with different matrices to correspond.
