I am excited to give this a try. As someone who did not study CS or MIS at school (in fact far from it, accounting & finance) I am open to any resource to assist code education online. I have found a few decent offerings such as w3schools.com, Mozila's p2p school of webcraft, and dreamincode.net but don't know if these will give me all I need..
On a side note if anyone has any other sites I should be considering, don't hesitate to shout them out!
Stanford has some top quality material up for CS. I have completed cs106a and am working on cs106b and they are both top notch!

If you are looking at more web based stuff then David Malan (Harvard) has some great free stuff as well.

MIT's Open Courseware is also top-notch stuff. The intro-to-CS and programming with Python has a set of lecture videos and assignments, I think there are a few others with lectures (including the famous 6.001 Structure and Interpretation of Computer Programs)
It doesn't look like these are what you are looking for, but projecteuler.net and programmingpraxis.com are great. I imagine these are more for maintaining and honing skills, rather than building them, but still great.
