Does [a-zA-Z0-9] (yes, I know [:alnum:] is the same) mean that there can be a number, but it has to follow a letter? Or would you just do [a-zA-Z][0-9] to do that?

That bracketed construction is called a character class. It represents any *one* of the contained characters. But not more than one. So there is no following at all, since for all intents and purposes the character class matches a single character (unless you use a qualifier like +, ?, or *).
