The very exhortation of the Angel Gabriel — "Hail, full of grace" - is absolutely an acknowledgement of the pure state of her soul.

Nope.

Only sinners need grace. The sinless can stand before God on their own merit; no grace is needed.

If Mary were sinless, she could never experience the grace of God.

Look up the definition of grace before you make untrue statements.
