You can do that from the Joomla administrator once you've got your site running.
This is for Joomla 3:
From the Administrator, pull down the Extensions menu, then click on Modules.
Find your slideshow module and click on the name of the module.
Once the module configuration is displayed, click on Menu Assignment then use the pulldown to set Module Assignment to "Only on the pages selected" then clear the boxes for all menus except Home.
