Caution: your advice didn't hold for Ethereum. When Ethereum forked, it didn't lose any value and Ethereum Classic value got created out of nothing.

Of course this stuff swings all over the place - you're as likely to get stung by some random swing in values as anything else I guess.
I'd be interested in knowing if this were the same with Ethereum (Classic), since I would assume it would put a large selling pressure on the minority fork (the greater the minority the greater the relative selling pressure).
However there's no saying what exchanges will do in this case.
If you have your own BTC you will have BTC and BCC after the fork which you can sell.
Yes. There was no replay protection (transactions were valid on both chains) but soon after the fork people created smart contracts that got initialized to a different state on each of the chains. So you could, e.g., send your coins to the smart contract which then would forward it to your address A on the first chain and to your address B on the second chain.
