Google for fingerprint brushes for Photoshop. 

The card for the mugshot can be the one sided square primitive resized. 

If it's a large sting operation, I've seen them use cardboard or sheets of paper with the info printed in black marker.  They probably do a more "professional" mugshot when they get back to the station.

Check out The Smoking Gun's website for celebrity mugshots.  That will give you an idea of what info is on the card.
