Hi!
While this is not a MySQL mailing list, I try to give you some hints and keep it short. There is maybe one important thing which should considered: clustered index. If use InnoDB you can think about to not using a surrogate key but a natural one which best support the query which you will use in most cases.An InnoDB table's primary key is a clustered index and querying against it is very fast.
