when you ran the checkout wizard, did you select the option to create the insert page, or did you uncheck the insert page?
if you uncheck the insert page (and dont create one) the insert button will not be added.
For the navigation buttons, they are not showing because navigation is not needed, there are only 4 results in the results set, all of them are being displayed, the navigation buttons will only show if there are more results than can be displayed on the page at one time.
