Some of Rippetoe's advice is a bit idiosyncratic…
I don't think bouncing is a good idea - better to go slow, or gently decelerate as you approach A2G. If you 'fall' and bounce, you're relying on the structure of the joint to trampoline you up again, rather than a co-ordinated neuromuscular process. Sounds like a recipe for disaster.
If your knees are wobbling laterally, I'd say that's a signal to lower the weight, or reduce the reps/sets (if it's happening after a few).
As for front squats, they're easier on the lower back, and tougher on the abs/intercostal stuff. Usually less weight than a normal squat due to the lack of assist from the posterior chain.
I'm not a S&C coach, so make of all this what you will.
