My b-hcg is 554.53. my last cycle was 36 days ago. the home pregnancy test seemed to be positive, but the line was really faint. i am pregnant, right?

Yes: It's time to call an Ob-Gyn doctor (or primary care doctor, if one does not have an Ob-Gyn doctor). The doctor or his staff can give details on when a newly pregnant woman should be seen, what lab tests might be needed, and for what symptoms a patient should call the clinic even if after-hours. HealthTap's site also has answers to thousands of questions about pregnancy. Do take prenatal vitamins.
