One of the controls you can also use is the sphereize filter in the Distort
menu. That will allow you to create or drop in a scan of a continent and
stuff. From there you define a circular area (Shift circle to get a perfect
circle)and then use the command. Set the control to 100 and it'll render the
surface on a sphere.

You can do a transparent gradient two ways:
1. When you double-click on the gradient box, go to the Edit button and
click it. You should be able to control the gradient of the colors and also
transparency...you can switch from one to the other.
2. Alternately, you can make a Layer Mask in the Layer menu, and start with
Reveal all..then you should have black as the foreground color palette. You
can do a gradient on this level from black to white and it'll be a
transparency gradient.
I also tried making clouds by having a white layer with a cloud mask, and it
worked pretty well.
