What's a good way to start learning how electronics and circuits work?
I'm told by many many people that  "The Art of Electronics" by Horowitz and Hill, is genuinely superb as a practical guide to everything electronical. Get version 2. Despite the glowing recommendations I've never yet seen a copy :-). But, I bought one at auction yesterday just to see if it was good as everyone says. I'm almost seriously wondering if I should write a book on the topic, but youd have to wait a while for that :-)

In the meanwhile, H&amp;H's book is actually a serious recommendation. 

I'd also join the PICList as a flexible resource where you can ask much less formally structured questions here and have general discussions. 

AND, as well, ask good single subject well described questions here about things that don't make sense to you.
