Yes
I second what Todd has said. I am currently working on receipt validation for my third app store app. I did not do it for my first two apps, too many other thinks to worry about. The documentation is not very good at this point.

And you also have add code to verify a valid receipt. There's a few samples of how to do this on github (you should modify them to make the app more difficult to crack unless you're giving the app away for free). Apple has more about this that you can read once you join the developer program.

Validating the receipt is optional.

Having recently gone through this with my first application, I generally would not recommend it for version 1.0 of someone's first app (unless it is a very expensive app). It is surprisingly complex and poorly documented, and there are too many other things to worry about when getting your first app through the approval process.

If you want copy protection (which is what receipt validation in about), I would leave it until the first update to your application or the second app you submit.
