The wizard is not re-entrant. You can create new pages with the wizard, but cannot overwrite existing ones.
Most likely the maximum records value is not being updated properly. Try updating it by hand... search for the number 5 in your source code and when you find the one that refers to the number of records to display, update it to -1. That should cause all records to be displayed.
You can modify the layout just as you modify any other html page in Dreamweaver using all of the tools available from Dreamweaver.
You may want to run the wizard again, with the same options and specifying different page names, then copy over the results page with the newly generated page.
Another option is, of course, to start over.
