If I were you, I would simply go for a medium size plane like the Lee Valley's low angle smoother or the small BU smoother. I would not spend my first dollars on a book or dvd to find out what I should buy. Why? The money spent on the publication would better go towards buying a good quality plane. Secondly, whether you get a block plane, a low angle jack or the planes I suggest, it won't be wrong as long as you use it, develop your skills and keep it in good shape. Chances are you are going to expand your collection to suit your work which may change.

Buy a plane and forget about books and DVDs (which may be good, but not for the purposes of buying your first plane).
