It sounds like you're off to a great start. One thing you may want to keep in mind is that there is likely a person living in your area who has attended one of Rip's seminars and has also taken a test administered by Rip to coach the lifting methods he describes in his books. A few sessions with that person can help work out any kinks in your movements and lifts. This may be a useful resource for you if you have any limitations performing any of the movements. There is also a SS forum and members will occasionally post videos and have other members critique the movement, but this is a less reliable method of achieving proficiency in the lifts due to the possibility of trolls derailing your progress.Yup, I'd already downloaded the free Amazon Kindle preview. It's incredibly generous, it includes the whole squat section. (Don't know if this is someone's mistake?)
It's great for learning the right form. It's much more comfortable having the barbell resting on muscle than one of your spinal vertebrae!
I probably need to work on the hip drive thing. One thing I really won't manage is getting my knees as wide as shown in the stretch/demonstration. My anatomy just doesn't work that way, and I have no trouble going low so hopefully that's not an issue. I'll keep working at it.
Stay with it and good luck!!
