re and all you need to do is the create an EVENT executing 'CALL my_sp()'
2) With all MySQL versions you can let SQLyog/SJA Notifications do. Notifications Services is an ENTERPRISE feature only. Schedule the job to run from the client (of course client machine must then be on!). Now try starting the wizard from the 'powertools' menu and you will probably find out. You can add an unlimited number of queries and won't need to run inside a SP.
