Just adding "Period" to the end of a sentence doesn't make it so.

Nor are the gravitational forces. Mass is absolutely irrelevant here, as it is can be removed from the forces on both sides of the equation. I know this can be tricky to figure out. The centrifugal force, in vector terms, is just the difference between the straight line (the route the object wants to travel due to it's current velocity) and the curved line (the one it is forced to travel).

Conclusion - weightlessness has nothing to do with the "cancellation", only with "falling" (in relative terms).
The moon, in this prevalent model, is an object with enough mass to create its own gravitational field (as opposed to any artificial spacecraft). But yes, due to orbiting, neither earth's gravity nor its centrifugal force play any significant role.
Trust me, the theoretical model of all this has thoroughly been checked and I doubt it will be possible to find any significant flaw with it. The only flaw is....at least as far I believe...it does probably not match reality.
