    Garry,
    
    I can help you with question #1.
     
    I've collected quite a few books on Celestial Navigation, first because I am a 
    certified bibliophile and secondly my wife challenged me to learn an abstract 
    concept on my 55th birthday...I chose Celestial Navigation.
    For a basic text that explains the method and the theory, I've not found one 
    better than Hewitt Schlereth's "Celestial Navigation in a Nutshell". Hewitt 
    posts on this list from time to time so if you have issues you can take them 
    to the source.
    
    My second choice would be "Practical Celestial Navigation" by Susan Howell. 
    Although this references HO 229, I found her text a good contrast to Hewitt's 
    book as I was learning, her life story is very compelling as well.
    
    I could see the concept and methods but the understanding was a bit shady so I 
    enrolled in Starpath's online course. David Burch and his folks do an 
    outstanding job. Having someone look at your work and lead you to a 
    resolution can save hours of head banging. It's not inexpensive but I found 
    it well worth the money and you can get your "stupid" questions answered in a 
    private manner.
    
    When you need some data to practice on search for "Silicon Sea", a set of data 
    produced by this list. Another option is "100 Problems in Celestial 
    Navigation" by Leonard Gray. Lots of stuff there to hone your skills on.
    
    Beyond that, this list can answer any navigation question that has an answer. 
    The folks on this list are quite literally the best in the world.
    
    Best Wishes,
    
    Ron Irwin
