It does. The gas law is an approximation. See http://en.wikipedia.org/wiki/Van_der_Waals_equation#Equation

As the guy pointed out above, some of the gas laws assumed ideal behavior when they were created. Ideal gasses are:
1) things that have no volume
2) Considered to be points
3) Very little interaction. If any, it'd be completely elastic
Course, nothing in our world is truly ideal and there are modifications to the Ideal gas law ( Van Der Waals, Redlich-Kwong, etc.) that take into account the fact that since it's matter, it takes up space, gasses have interactions that are inelastic, etc.
In short, the size of different molecules don't come into the BASIC gas laws, but they do in the more advanced treatments.

Because they are so much smaller than the average space between the molecules.
