Here are my answers:

1. Most modern mobile phones does not have any limitations. You could use as much memory that is available on the phone. But the MIDlet should be kept as small as possible.
2. See 1
3. Yes, use the JSR-75 API
4. If you use the RMS API, the data shall survive a power loss. All MIDlets have access to RMS. If you store in a file it is also kept during power loss.
