The plan is to have the planet in the upper left look like the map (at least roughly), but that will take a little more work (mainly because I didn't structure my map-creation code right to make it easy to get the planet's texture from it).
The maintenance numbers and other figures may or may not end up in the final game. Originally we were going to have a simple model for those kinds of things, but even that may be too much micromanagement, especially late in the game when you're not really interested in what's going on on each planet. But, as it currently stands, Solitair is on the right track: every improvement you place on the planet employs a certain number of people, creates so much industrial output and/or food, etc. And of course there will be governors to take care of building stuff for you if you don't want to deal with the minutiae.
