Redhead,
Welcome to the Forum and the Class of 2014.
I trust you have been researching the Forum and planned accordingly.
However the Camino leads...you can expect an experience like no other. We look forward to you keeping us in the loop.
Oh, BTW...three days is plenty of time to remove everything from your pack and removing anything you think you "Might" need. The Camino is NOT wilderness camping.
The last night before you leave...repack again. This time REALLY taking anything out you think you might need.
I and the rest of the Forum, I am sure, would be interested in the specific "might need" items you are wise enough to remove.
In my case, I removed a corkscrew.
Buen Camino,
Arn
