I read that most solutions have a pH between 0 and 14. However, if I add 1 mol of H2SO4 to 1 liter of water, I think I should have a pH of -0.3 since there are 2 H ions per H2SO4 molecule.  Is this correct? and a following question, if I add 2 moles of H2SO4 to 1 liter of water I would have -log10(2(2)) = -.602, right?? So does this mean that the pH can be less than 0 and I assume grreater than 14?

Ph range between 0 and 14 is a crude approximation. Assumption that 1 molar H₂SO₄ dissociates completely is also the approximation usually accepted for preliminary levels of chemistry (but this is a false assumption).

Simply put - yes.
