At the bottom of one.htm it asks you whether you've finished reading the instructions; to which you answer the affirmative.

one.htm also states that only slight modifications are needed between the two sections (only one letter needs to be inserted)

Yeah, that's how I managed to guess the second page, but I don't really "get it". Are these suppose to actually be mechanically derivable, or is this just a guessing game?

So far they seem like riddles to me.

It's basically a sequence of riddles. Not a technical challenge.
