What do you mean by "in sync with their orbit"? You want night and day rhythm? The math for rotating the planets is really quite simple. (Just sine and cosine once in the sun's frame of reference and once in the planet's. Elliptic orbits would definitely look cool. )
The force fields could get interesting though. Can't you just tell Unity to attach force fields to the planets?
It's nice to see some progress on this.
