I just wanted to put in a plug for the Starting Strength book and DVD for a newbie lifter. I've been doing crossfit for almost a year but was frustrated that my strength gains were plateauing so I decided to start SS on my own in addition. From crossfit I had instruction on form for back squats, power cleans, deadlifts and presses and still reading the book and watching the DVD helped. I have video taped myself a few times working on fixing some form problems that are preventing me from getting to heavier weights. The forum on SS is also great for critiquing form and offering suggestions - but you really need to read the book first - they can always tell when you don't and are asking for advice anyway
