...but I have the private key ONLY. No public key, no public & private QR codes, etc..
what are the step-by-step instructions on how to go about using my private key only to transfer funds to a newly created wallet?
1. Create a wallet on blockchain.info.
2. Go to "Import/Export", and enter the private key in "Import Private Key" field.
3. Send your bitcoin to your newly created wallet.
You could use other wallet clients as well, but I think it would be easiest to use blockchain.info.
