Are you suggesting that there shouldn't be a period at the end of any of the points, or that there should be a period at the end of each of them?

I put a period at the end of 5 because it's a list that follows a colon, which would imply that there's a period at the end of the sentence--and that end would be the end of the last point in the list. Though, I thought that semicolons at the end of the other points (plus "and" at the end of 4) would probably decrease readability. So, I left said semicolons off.
