Is “bed her in” the same as “bed her”?

No, "bed her in" (in this context) is like "running in" a new car (by driving it cautiously). Or when you get a new pair of boots, and they're stiff because they're new, so you wear them around the house. AKA "breaking them in". Getting something established. Settling in. Obviously, it has the double-entendre in this clip too.

Nooooooo! It's about someone getting accustomed to something new. 'Wait for it to bed in' means waiting to something or someone to adapt to a new situation.

"Bedding someone" is sex.

Excellent show, enjoy!

Before watching this clip, I had never heard "bedded her in." This is a play on words - perhaps created for this particular scene. It is not a common phrase. Without context, it's not entirely clear, but she may be referencing the idea of taming a horse "breaking her in." By swapping the word bed for break and changing the form a bit... it becomes "bedded her in." The idea being that by taking her to bed, you might be able to tame her.

This is a play on words. "Bed her" - have sex with her. "Bedding in" is a common phrase, especially in UK English, for "Carefully operating something that is new until it works optimally". Other similar terms used are "running in" or "breaking in". Usually it's in reference to specific things like * Bedding in the new brakes on your car * Breaking in a new pair of leather boots * Running in a new engine (e.g. in the movie *Titanic* when the Captain says "I prefer not to push the engines until they've been properly run in" Obviously here it's in reference to a sexually inexperienced partner, and so "Bedding her in" both refers to having sex with her, and also making her more sexually experienced.
