Clicking on a field in any of the examples will automatically take you to the parts of the style where you can make some changes.
You can then start to make some changes, such as choosing the "short" or "long" version of the name (with or without the first name), or replacing the first name with the initial, by enabling the initialize-with function and adding a period.
If you just try to italicise the titles directly, you will see this warning:
because you will italicise the titles of reports, but also of chapters, PhD theses, etc.
For some item types, the title is already in italics. The item type "report" can be added to the conditionals for these item types.
