I've been asked to provide a concise list of the items that are covered more extensively here:
http://www.odusergroup.org/forums/index.php?topic=1682.0
1. Base z/OS Operating system
a) USEZOSV1R9RULES(NO)
b) MEMDSENQMGMT: ENABLE
c) COFVLFxx parameters that, at a minimum, should be specified
2. JES2
a) auto-tuning of the JES2 checkpoint (at Z22 mode):

3. zFS - At z/OS V2.1 a new version or release was made for zFS V1.5 or V5
If anyone has any additional please append or drop me a note.
