I would also assume there'll be structures/crops/what have you that will need to be bought with Mojo instead of coins. It'd then be up to you if you wanted to level to attempt to get that much, or to buy it outright.
As it stands, the only 'structure' that I can see in the store so far requiring Mojo only is the Gryphon's Nest for 20 Mojo.
To put that in perspective, I'm level 3 and have 6 mojo right now. Seems you get mojo for levelling up and for achieving certain goals.
Oh, and Stuffradio? I believe to move stuff around, you click on the build icon, then there should be an option for 'redesign' at the top of that screen, next to the ads. I believe that allows you to move stuff around.
