I want to get my friend a cool gift and stick it in her stocking so she can receive it Dec. 25 (when I likely won't be online).

However, I want her to know that it's from me (I'm selfish like that). My question, then, is will she know who gave her what or not?

Yeah when the stockings open it'll list who gave what.

That's good to hear. ^_^ Thank you very much!
