Here are my answers :
But, how do I create and populate the initial set of tables that CI needs?
You can use any existing database you use for running limesurvey in its current form i..e v.1.91+ . Although some users have problems with using 1.91 database. So, i would suggest you to use 1.92 database. Installer for CI version of limesurvey will be integrated later on.
What will the default admin password be?
Most probably , "admin" and "password" if you haven't changed it for the database you are using.
If you have any further questions, feel free to ask.
