Recommendation letter from professor. She's asking for CV?

So I was asking my professor for a recommendation letter for a school I want to apply to. She said yes, but she also wants my CV or resume, transcript, and a statement of purpose to be able to write the letter better. I was just wondering for the CV, would it be addressed to the reccomender? Or is it to the college? Also is it okay to ask the same professor for recommendation letters to multiple colleges? I feel nervous to ask for so many.
