The free Proko videos on YouTube are not bad as well -- maybe a good place to turn once you have a few of the basics in hand -- in particular, the artistic anatomy videos are helpful if you get into drawing humans.
In regards to digital art, I recommend the opposite. A sketchbook and a few pencils can be had for far less than the cost of a drawing tablet or iPad, and the physicality of drawing with analog material is, for some of us at least, part of the appeal.
Lastly, try to draw every day: from life, from memory, from imagination. Take whatever classes appeal, for sure... but in the end, the time you put in, drawing things that interest you visually, is what really makes the difference in the long run.
