Great site for intro lessons on fingerpicking and reading TABS. Instructor is laid back guy with his two dogs, Lick and Riff always on the couch with him as he teaches. Even a simple tune sounds good doing fingerpicking style.

More advanced fingerstyle. Only a few freebie songs. Keep this one in mind when you want to purchase an advanced arrangement after you learn to read TABS
This is a short list of what is out there on the web. Should ruin your fingertips in short order. Happy strumming
