You can change the paragraph spacing on the Page Layout tab of the ribbon, and then use the Update <style name> to Match Selection in the Styles pane; rest the mouse pointer on the right of the style name and click the arrow to see the update (and other options).

To display the Styles pane quickly, you can press Ctrl+Shift+Alt+S.

In addition, if you want to change the indentation for bulleted styles, click the actual list bullet to select all bullets of the list. Right-click and choose Adjust List Indents. This change should be automatically incorporated into the style (but you can use the Update... command anyway, just in case).
