I don't know all the things the CICAL and CMIME service books control, but I do know if you don't have the CICAL service books you will not be able to send and receive calendar invites.
Also, I learned the other day that the specialized email folder icons, such as for Yahoo and windows live/hotmail are pushed with the service books. I noticed my icons had reverted to the default the other day, though email was working fine. I resent service books and the icons returned.
Bottom line, if you are missing the CICAL and CMIME service books you should resend service books just because you don't know what all is going on with service books. Just because you don't realize anything is wrong doesn't mean all is ok. And if you keep losing service books, you need to figure out why.
