Go to 501st.com and find what Garrison you belong to based on where you live. There should be contact info there for your GML.
From the pictures, it looks like you have been to a troop in your area. I'm sure one of the other troopers in the picture could help you get in touch with your GML.
Also, check out the CRL on 501st.com. A backpack is not required for basic approval. As long as you meet the basic CRL requirements you'll pass just fine.
