You can specify that you want more tiles here: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk. (2) In the search box above the list, type or paste '''newt''' and pause while the list is filtered (3) Double-click the '''browser.newtabpage.activity-stream.topSitesCount''' preference and enter the desired value (normally it's either 6 or 12) and click OK As for changing the order, I don't know of an easy way. Drag and drop doesn't seem to work. There is a preference named '''browser.newtabpage.pinned''' which contains the URLs of the existing pinned tiles. Editing this preference in about:config has no effect, but if I exit out of Firefox and (carefully) edit the '''prefs.js''' file where the preference is stored, at the next startup my new order is reflected. This hopefully will just be part of the interface in the future.
