Discussion of off-line secure computing, paper wallets, backups etc are beyond the scope of this post. I am aware of what steps to take. I also give these steps a lot of attention.

I would like to create a bitcoin address using dice. I don't want to trust software and/or hardware RNG. I don't want to memorize anything. Therefore, I don't think Diceware is appropriate. I also want to prove to myself that my manual RNG is good. I also want to minimize potential issues with the human factor (me). I want to keep things simple.
Should I roll the equivalent of 256 bits of entropy with a standard dice (# of rolls?), and sha256 hash it for the secret exponent? What is a secure method for generating the bitcoin address from there?
I would then import the private key into Bitcoin-QT for spending (out of scope).
1. Is this a good approach?
2. If I append "1", "2", "3" etc to the original series of rolls (seed).. does this constitute a "secure" method for generating a series of addresses?
