Yes that site you given about third heaven and structure of things I very interesting, and seems plausible. However as I got to the verses which they used to back their claims and visions of water or frozen, glass or what ever you want to call it, does not match well with the context which it was written. Therefore making their theory with relevance to the bible invalid.
FOr example, eziekiel; what I thought he saw was actually an advanced technology craft. Rushing waters(engine running) , helicopter like (angel wings) which dropped as it stopped moving.
"And before the throne there was a sea of glass like unto crystal: and in the midst of the throne, and round about the throne, were four beasts full of eyes before and behind."
(Revelation 4:6 KJV)
Read before this it says,
4 1 After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be h ereafter. 2 And immediately I was in the spirit: and, behold, a throne was set in heaven.
Therefore this vision was already set past the heavens door. Making rev/4 verse questionable, whether the sea of glass is really outside or inside.

The 3rd heaven is where God resides. Paul mentions only a third heaven. He doesn't seem to acknowledge any more (as some Jewish beliefs)
Here's a really good article including the 3rd heaven:
The Third Heaven is above this higher "Sea," and this higher sea is before and below the Throne of God:
