1) Depending on the ROM version, Palm may have already included the camera patch. If you notice your battery drains after using the camera, install it, otherwise don't.
2) The Palm OS is not a multi-tasking environment. Essentially when you open a new program the previous running program is closed. Bejeweled and other games save the "state" that they're in, nothing more.
3) Contacts are stored in main memroy. Depending on what program you're using for email, you may or may not have the option to save messages on a memory card.
