Scented candles, or something sweet that isn't too overwhelming...I used to pick White Lilacs and leave 'em in the dinning room for some aromatics; the main idea is to infuse their senses before anything.
I suggest a scary movie, but not too scary; so, go with a Thriller...something to heighten their heart-rate, it's been Psychologically proven to get women to associate you with an ideal impression.
Shoes...seriously? Yes, seriously...tidy up your shoe area and show off the Collection if you have one. They're drawn to feet. Do it.
Put the smallest amount of Cologne on your wrist.
Welcome her with a joke, it'll help take the edge off if there was one.
Don't talk too much, alternatively get her talking about herself as much as she seems comfortable with; don't push subjects, but lead her with some of your interests so she can tell you, one way or another, whether she wants to enjoy them with you...it also gives her fantasy ideas about you two together.
Speaking of which, talk about travelling with her...well not with her, with her, but that you plan to travel; also inserts fantasy in her mind about doing so with you; makes her associate you with long-term commitment.
I can go on...these will be sufficient for what you're looking to accomplish
