I've been to bitaddress.org, created a wallet and printed it. Before I transfer my BTC I wanted to double check that this is a legit wallet generator... most of my $$$$ is BTC.
How about the other coins? Most are low balances. I think MUSIC is now worthless, but nonetheless, I might ask well keep them!
You doning it quite correct way. To simplify things, convert shitcoins to one coin BTC, then one paper wallet or split it to couple BTC paper wallets for extra security (bad luck mostly from someone else using same address, almost impossible but still why risk

).
