I found this site online - for $20 you can download a how-to book on grooming...
http://www.ebooks.com/ebooks/book_di...asp?IID=255412
This site also has info on grooming (read further down for nail trimming)

Hmm... this site actually looks really good... even has info (and pics) for ear taping..

Hope this helps!
