Hi eharvey and welcome to the forum.
You SHOULD be able to download a NASA satellite picture of any area you want, but there's a bug at the moment - see this thread:
http://www.airnavsystems.com/forum/index.php?topic=6798.0When it's working, set up the view you want on your map view then press Ctrl-D, and give the image a name. It will then appear. It's a normal image, so when you zoom in, it pixellates. Because of this, I normally switch to full-screen map view first so that it captures a big image.
For setting up points on your map, you need Custom Legends. Get the lat/long in decimal format (I use Google Earth for this), and enter them in the format specified in the File...Preferences...RadarBox tab. Then make sure that the display of Custom Legends turned on in the Map menu.
Hope that helps
Rod
