You can get any and all replacement parts from Autoharp luthiers. I have several recommendations:

http://www.autoharpworks.com
Bob Lewis's Autoharp Works, where you can order single strings, just the ones you need, instead of a whole set. You can browse through specific strings, and his FAQ section is great.

http://www.daigleharp.com
Pete d'Aigle's A Different Drummer, where you can order any and all supplies you'll every want. You can order single strings if he has them on hand. Go to the publications section and order The Autoharp Owner's Manual, a must-have if you're going to keep your instrument in top playing condition.

http://www.autoharprx.com
Chuck Daniels's site where you can order what you need, but you have to have an idea of what you want. Prices aren't generally quoted on the site, but send him an email and he will get back to you. Be sure to look at his Workshop How-To's. Chuck is very helpful.

These three gentleman plus the Autoharp Owner's Manual helped me learn to dismantle, refurbish, and customize Autoharps. I also order from Elderly, but I spread my business around. I've ordered lots of supplies to refurbish and customize Autoharps for developmentally disabled children and adults. You can see one of my Autoharps at http://www.xable.com/blogs/autoharp. Another is posted at http://www.alanhorvath.com/moody_blues_harp.php.

For fingerpicks, books and Autoharp CD's, Visit Autoharpquarterly.com and go to the marketplace.

Last but not least, go th http://www.autoharp.org and join the CyberPluckers. While you're there, look into the Autoharp festivals and see if there is one in your area. We're going to the Mountain Laurel Autoharp Gathering (mlag.org)in June for a week of workshops and concerts. Very affordable!

Feel free to contact me if you have any questions.
