Answer to your first:

Both temples were buried in sand...nature's way of protecting. See the base stones of G2 and G3...same finish, but none have a high polished surface.

Second:

You quote: "...Quote: The temple was laid out in almost a square ground plan. It is situated just next to the Great Sphinx and its associated temple...."

The south temple has its north side built on an angle...the north temple has its south side built on an angle...what is the author thinking about? Neither forms an "almost" square. The design is intentional and the angled sides align parallel with the causeway for a reason.

Best.
