re: Am I right or am I wrong here?
"Necor Buldon Slock" = "Danger Rocket Explosion"
"Edwan Mynor Necor" = "Danger Spaceship Fire"
"Buldon Gimilzor Gondor" = "Bad Gas Explosion"
You are right. "Slock" means "Rocket."
It's a simple logic test, and Ron is being too cute with his interpretations. If "Slock" meant "Gas," the word would appear in the third phrase. If "Slock" meant either "Danger" or "Explosion," it would appear in one of the second two phrases.
