The auth methods A and B are two methods to authenticate to the chip on the Smart card. Most times you can set permissions on data blocks which can differ depending on the used key. (e.g. key A allows read-write to the data block, key B only allows reading) This is defined in ISO/IEC 14443 if I'm not mistaken.
For your second question, I guess you set util.debug
to true at the beginning of your code
