Rub Out the Flakes?

[schnell987]

Sorry for the newb questions, (I've read the threads here and performed a few searches already) but...

1. What does it mean to "rub out the flakes"?
2. I bought two tobaccos the other day. One consists of numerous strands of tobacco (like confetti) while the other comes in thin sheets. Are there different methods for packing the bowls depending on the type of tobacco?
3. I bought a cheap corn cob to practice with. However, the most prominent flavor seems to be burnt wood (and that is not the flavor described on the tin ). I this because the bowl is burning until enough ash accumulates around the bowl?

Thanks in advance for your help.
