1. That depends on what you

1. That depends on what you want to do. You should never change core modules. If you want to change the default behaviour you should check for contrib modules that do what you want or write your own custom module or functions. You should also avoid editing contrib modules without contributing back to the project (think about what would happen when you need to upgrade).

2. Check the readme documentation about multisite. Basically, you need to add a new folder for each site with their own modues and themes folders and a settings.php file.

3. Sounds like something could be wrong with the rewrite rules? I remember the first time I installed Drupal I had some trouble getting the .htaccess right.
