Late response to your question on aches, pains and injuries.
I had a couple of issues for 6-8 months. Been over some of this before, but... I think I have a tendency towards getting shin splints- at the peak of doing T3 the soft tissue by the shin bone was painful to the touch. Also my knees started clicking alarmingly when squatting, and I started getting sharp pain sometimes in the tissue around the bottom of my knee caps. Both the pain in shins and knees and the clicking were resolved by 3-4 very painful sessions with a foam roller (on the shin and the IT band). (I guess I should add that Miaou suggested that the clicking was likely caused by patellar mis-tracking.) For some time I found that the shins tended to be rather painful when I did foam rolling, but lately after reading a post of GBGs, I've added band foot dorsiflexions, and now one shin is not painful when rolled at all, and the other only very, very slightly. I guess I try to stretch my quads after doing squat or deadlift sessions, too.
The other issue I had was huge knots which I guess were towards the top of erector spinae, on both sides. On occasion they would actually really tighten up and become quite painful. It would feel like there was a really tight line running all the way across my back across where the knots were, almost to my ribs. It's speculation on my part, but I suspect that these tight areas might have contributed to a few issues I've had lower in my back. These are now much better thanks to rolling them out with a baseball.
Edit- forgot to mention that my lower-body foam rolling was on the IT band, too.
