Are all the maps free or do you need to buy them as well?

All free. Whatever you see in Google Maps is what you can download (terrain, satellite, topographic, road/street, etc). Just don't try and do TOO big an area for the satellite ones, and don't try to get in REAL close. I think from memory the highest "zoom scale" I go down to is 16, and so far so good.
All the others are good at whatever zoom scale you feel comfortable with.
Cheers.
