I cant remember if the other colonies were all destroyed by now or not (been a while since I read the books), but you're probably right. There may be other inner colonies left, but Reach was the last Defense before earth, the other colonies are pretty useless in defense against the Covies. Plus they've been looking for earth and earth only, so once they find the coordinates (like we know they have) they'll go straight there, regardless of other colonies.
