After getting your account opened(waiting 10 and 20 minutes and confirming through email) you need to apply for level 2 access to the site. After applying for level 2 you will have to fax or visit the closest usda service center(you can google for a list) to show them your ID and they will verify your level 2 access.
Next you will need to login to your usda account and apply for forms PPQ587(free) and PPQ621($70). I'll apply for both next week and tell you about the forms and process after filing the forms, etc.
If you need help call the APHIS main office in Maryland. They are very nice and very helpful and very thorough in their explanations.
