1. Perhaps your load was lower than your average workout. As you progressed, you got stronger and thus didn't feel the soreness.

2. My forearms are actually thicker than my biceps (not triceps). All I do is pull, squat, rush under and push really hard.

3. I wouldn't have followed this program ever. Ever. It seems he addresses issues like flexibility, mobility, stability/balance, with the help of the bent presses and deadlifts to build total strength. It seems to be built for people who lack time and access to more equipment or guys that want to build this wiry strength kinda thing. I believe in specificity in getting stronger, but I also believe in ample supplementary movements. I'm not quite the advocate of a Bulgarian/East European style of constant max.

4. No shit Sherlock.

5. Overtraining doh. I got it when I was training about 3 hours per sessions, 2 sessions a day, 6 times a week.
