Jay, you can try spraying her with some water and see what happens, some greys like it and some don't and you will find out real quick which one she is, if she doesn't like it then you will have to wait until you can handle her to bathe her.
If her cage is big enough she can flap her wings inside her cage otherwise you can open her door and see if she will come out. Leave all her food and water inside her cage so she has to go back inside for it.
Chirps are usually just grey communication and it could mean a variety of things, just common grey sounds.
I do not know of a safe air freshener to use around birds, their respiratory systems are very sensitive so we don't use those products. Birds usually don't "smell" although they do smell like a bird but it is not an unpleasant smell and you have to be right up against them to notice it. Personally I like bird smell but then that is me.
