Greetings! I just finished working on a boom chick finger picking lesson taught by Ben Lindholm. Check out this link and here is another one for you as well. Also, just type in "fingerpicking" next to the forum tab and a variety of lessons will come up. When I fingerpick I usually anchor my pinky like you described. I would be interested to hear why this may or may not be a good idea myself. Talk to you later.
