Tobias-
I mentioned a young woman who has a graduate degree in Electrical Engineering from MIT (Limor Fried - a.k.a. "Ladyada").
She created a company called Adafruit Industries. They make DIY electronics kits for beginners. All the instructions are online - they've got videos and tutorials with pictures.
Here's the company website:
http://www.adafruit.com/Here's her own personal web site:
http://www.ladyada.net/The Arduino project is here:
http://arduino.cc/
Here's a link to lots of stores that carry the Arduino microcontrollers (and others, too):
http://arduino.cc/en/Main/BuyOh - that "Illuminato X Machina" device - the code update video - is at:
http://www.liquidware.com/
Try these sites for beginner info - they've got lots of electronics theory (your "why") - and some "how", too.

I'd also suggest that you get your hands on "Make" magazine. It's chock full of wonderful electronic goodie goodness. I'll be glad to loan you some of my back issues.

Also, I've got some soldering irons and other tools I'll be glad to let you have to get you started. Over the years, I've upgraded to some pro or industrial level soldering irons - but I've got a number of old ones that will get you started. I've been soldering for years and years, and I can show you the right techniques. But, of course, you have to practice and eventually you'll wire something up wrong and release the magic smoke from the inside of some kind of components. You just haven't lived until you've smelled burning silicon from a device you fried by your own wiring mistake.
Right now, I've got my kitchen table set up as my workbench - you're welcome to come by and check it out. That offer is extended to anybody in the JUG who's interested in this stuff.
