Jot down notes as you go if this is the first sock, so you can do the same on the second sock.
From what you stated it all sounds correct to me. Some socks have you work the heel over an equal amount as the front, others don't. Just so you dec back to the original 52 sts I don't think you should have any trouble.
I have not made any socks recently but I was happy to find that website. It will allow me or anyone else to make basics socks without being tied to a pattern. As long as I know the math formula part of it, I can pretty much figure any of it out.
Good luck and let us know how it works out and post a picture if you can.
