What are the best math instructional sites, resources and (especially) tools for graphing and math visualization these days?

It's been over 20 years since my mathematical high-water-mark (college calculus), but I'm trying to get the ol' brain back in shape. I'm working my way through algebra, geometry, and trig once more, with the goal of eventually getting through calculus in a classroom again. Also, I'm a homeschool parent and my kids aren't that far behind, so this question might help me teach them, too.
Back in the day, we had non-graphing calculators and had to do all of our visualization on graph paper or mentally. Outside of class time, our resources were limited to the textbook and the teacher's office hours. I hear a lot's changed -- something about "computers" and an "information superhighway"? What are some good online & software tools for helping me get it as I pursue these goals?
I love Vi Hart, but she's more dessert than main course. I've dipped my toe into the waters of Khan Academy and found it helpful, but it seems to lack the organizational layer a textbook would have. I've heard of Wolfram Alpha but don't really know where to start. Tips on getting the most out of these resources are welcome, as are any stuff I haven't heard of. Free preferred, but excellent paid resources welcome too.
For the record, my primary computer is running Linux, but I have access to machines running Win7 and MacOSX, too.
