lol. The script is for use on your PC to build maps, not your tablet. You build the map file on your PC using the script and then transfer the completed database to your tablet. It's also currently only for Google street, although it shouldn't take much to hack it for other uses and other repositories. As for the zoom levels, I've just found it best to do the even numbered zooms only. For one it's a lot less zoom levels to download, and two, unless you have a need for any zoom level higher than 16 or lower than 6, you should only need 16, 14, 12, 10, 8, and 6. The only time I've found that 2 and 4 come in handy is if you're adding a lot of POI's, but otherwise under practical driving use, they're really not that handy and take up a ton of space for something you really won't use that often.
