IIP is just the front page with custom boxes and no forum main index. Siderbar IIP is a Sidebar that shows up in any forum page unless ya use $config['iip_call'] = 1 on that particular page. Also you will need to set the generic placement of the IIP sidebar in the admin->themes config and you will need to set all CURRENT users to either right or left depending on where you want it initially using a query such as
UPDATE U_Users SET U_Sidebar = 'left'
