Helen, Here's a book that might be of interest to you, From Lute To Uke: Early Music For Ukulele (Book/CD Package).
It seems to be fingerstyle playing and has some Dowland lute pieces in it. It starts out easy and progresses in difficulty. A friend mastered the first few pieces in about a week. You can find a number of homemade videos on youtube of folks playing arrangements from the book.
