You can actually do this in the Paragraph task pane. Select Hanging from the Indent drop-down list, and then set a hanging value of 25px.
Keep in mind that this will only look good for single-line bulleted list items. If the item extends to multiple lines, you'll get the actual hanging indent effect.
The other option is to go modify the XSL. You can create the hanging indent first, and then remove the PADDING that was added, and just leave the TEXT-INDENT.
Good luck!
