dean,
Re. p-factor - see if you can borrow a copy of "The Compleat Taildragger Pilot" by the late Harvey S Plourde, ISBN 0-9639137-0-0, published privately by his family. There's an appendix which gives a very deatailed mathematical explaination of p-factor - far more detailed than you'd need as a pilot, but it'll answer any questions you've got as long as you can fight your way through the maths!
