A couple of questions about setting up mysql?

innodb_additional_mem_pool_size - the amount of memory allocated by InnoDB to store various internal structures. If InnoDB does not have enough of this memory, it will request memory from the OS and write a warning to the MySQL error log.
I don't have such a value in my.cnf. What is the default in this case and what goes into the error log?
innodb_buffer_pool_size - the amount of memory allocated by InnoDB for storing both indexes and data.
Also in my.cnf there is no such setting at all, what is its default value in this case?
Where, how to see the state variables Key_reads and Key_read_requests
