It's a remedial geometry textbook by today's standards; most HS geometry
curricula go much futher. The point of Ayil Meshilash was to introduce
bachurim to geometry, not to be some major breakthrough.

You can judge for yourself. See <http://www.hebrewbooks.org/20713>.

Also, I can not find a Cramer's Theorem or Kramer's Theorem in
the mathematics of inifinities. In fact, the whole concept of doing math
with infinities is generally accredited to Georg Cantor, in the papers
her wrote between 1874-1884 -- a century after the Gra.

I found Cramer's Rule in linear algebra (already discussed). Which had
some false positives because there is discussion of how to extend it
to an infinite number of dimensions. Still, not the Gra.
Cramer's Theorem in statistics, by Harald Cramer (20th cent, Sweden)
Cramer's Conjecture about primes, also by Haral Cramer.
Cramer's Theory in Quantum Mechanics.
And lots of references to TV economist's Jim Cramer's theories, but with
a show titled "Mad Money" you know that he's looking to stir up interest.

I have to agree that this whole thing appears to be an urban legend.

Tir'u baTov!
