I don't really understand the three equations of H2CO3+H2O in the end of this page, either.

What does it mean by," because harder to lose H+ from negatively charged ion(HCO3-)?"

Same here! Also, is it true that Ka1 > Ka2 > Ka3 implies that H2CO3 has less acidity than HCO3- ? If so, why would this be true?
