Yes, you get everything. The extra $15 is only if you need international shipping, since shipping outside of the continental U.S. costs lots of monies.
As for the civ-creation (sorry I didn't answer you immediately, I'm having to put most communications on hold ATM, and I'll probably be pulling an all-nighter tonight to attempt to finish off this tech demo - I've prepared by buying enough energy drinks to keep me in frothing-gerbil mode for the duration), as I've said to other backers, you won't be restricted to merely 'leader name/aggression level/government type' - although naturally those WILL be the first things that are defined about your civ, since fleshing civ code out will take a good deal of time on my end. I'm erring on the side of 'put in as much detail as you want, and I will try and gradually make the civ generation systems robust enough to include most of what everybody wants in their civs'. Depending on how complex you make your civs, some really crazy stuff might be undoable, but I actually encourage you to put crazy stuff in. There's a reasonable chance I might go 'holy crap that would be awesome' and actually create crazy code for it.
So, yeah. You WILL get a survey asking you for the mandatory stuff that I'll need to initially put your civ on the map at all (rulers, important figures, religion, cultural traits, yadda yadda). You'll also get the chance to write up a big, huge description with tons of caveats, and I will slowly try to address as many as possible over time.
