Welcome aboard the RoadTrip America forum.

Well, we have a whole raft of resources on Road Trip Planning, and even more on execution. A few of the basic ones that are practically "musts" for your case would be for you all to take the RoadTripComparability Quiz just to make sure that you and your friends are clear on (and agree on) the goals of the trip, particularly if you take the Focus. And these two links (Trip Cost Estimates, and Fuel Cost Calculator). Those should get you a pretty good start on setting up your own ideal Road Trip.
