To answer your questions:
1) volatility trading is very complex. If you are serious, you need to spend a few years understanding and trading vanilla options, then move on to more complex products like VIX and VarSwaps. To trade volatility without any theoretical basis is an invitation to disasters.
2) volatility is not mean reverting. Yes, if you pull up a historical vol chart, it looks like it's reverting. But in reality, you trade a fixed maturity vol. You can trade a fwd starting VarSwap, but there's a whole bunch of other issues. (Capital, MTM, Credit etc...)
3) I recommend reading Natenberg before you start. It's the bible for most options traders.
