1. You *have* to reboot *each* time a kernel is updated.
2. You *should* update regularly, not just from one major version to next major version. If you wait that long with updating you are asking for trouble. (Because of security holes that you don't fix and because an update from one major version to another may have a few more glitches than going with all the minor updates in-between.)
