1) I was able to also get WA intern license without HIV/AIDS education and training. But, here is the WA link for recommended AIDS training providers. HIV/AIDS Prevention - HIV/AIDS Trainings for Licensure :: Washington State Dept. of Health
2) You can just print the score online since, you have not received the certificate yet, the score should still be available online.
3) Just submit the FPGEC certificate. That's all that I submitted and the $30 check application fee. Then, they will send you a fingerprint card. Do not fold this, use a hard envelope. You can do the fingerprinting in your sheriff department. The fingerprint technician should do a good job. Then mail back the fingerprint card together with a fee to WA Board of pharmacy. Wait for less than a month to receive your license.
Hope this helps you.
