Good job in posting up a game 
Building basic improvements on tiles with resources you are yet to research the required technology for is fairly common practice: farming / cottaging / mining AH or Calendar resources especially. The idea behind it is the bonus food / commerce the resource tile yields in itself. Whether you replace it later with the correct improvement is up to the situation, really. You wouldn't necessarily tear down a town to replace it with a plantation. In this case you're probably better off researching AH as well, as your second city is likely to get the sheep N. It's not a great city but it can whip and chop so it's still worth settling.
Totally agree with Jastrow on the Great Lighthouse although a learning game probably shouldn't be about building a broken wonder
