Those old Larsons look pretty nice, but unless you have lots of time and lots of money, your daughter will be in junior high before you get that thing on the water. Sharing boating with younger kids is magical, and it can give you some of the best time together, but you won't have much of that if all your free time is spent out in the garage rebuilding the boat (or working so you can pay someone else to do it.)
I think Scott Danforth's estimate of $6000 (not counting the cost of a motor and a trailer) is fairly accurate. Add to that several hundred hours of labor (probably 200-300) and you have an idea of what you're facing. I really enjoyed restoring my boat, but it needed quite a bit less than your All American, and I was fairly handy with tools already. If you don't mind the work and are up to it, it can be a very rewarding process. But if all you want to do is get on the water for fishing and boating around there are cheaper ways. Look on Craigslist and expand the radius of your search, and I bet you'd find something that is ready (or nearly ready) for the water.
Good luck!
P.S. The windshield, if intact, on that boat may be the most worthwhile part of it. Those old windshields are hard to come buy, and you often see folks looking for them as they restore or repair older boats. Selling the windshield alone might help get you closer to your goal...
