I hadn't heard about BCC before. I've been researching it for about half an hour since I saw your post. I'll be looking into it more closely tomorrow.
I don't advice anyone to use any obscure unknown wallet in the hope of receiving some BCC at this point. Only trusted wallets should be used at this point and BCC need to be accessible through these trusted wallet...
Yes. But what you need is your private keys for your BTC addresses. If you don't know what those are then it's a good time to learn. Private keys underpin the cryptography of distributed cryptographic ledgers like Bitcoin, Ethereum and Steem.
I know what they are. I'm currently using Electrum and I still have a bit of Bitcoin left on exchanges.
I'm currently in the process of bringing them back on my Electrum wallet. We'll see how things go from here.
