How much of a tax deduction can I get for donating at the goodwill?

Hi, alright -- so I donated 200 leisurely books, college text books, and some children books, a nice computer printer, a computer keyboard, some clothes, shoes, belts, and stuffed animals. Would anyone know how much I would get back for that? I'm a college student who makes less than $20,000 a year in Florida.

Second (main) question: If I use the H&R Block easy tax thing, can I still submit the donations in my name?
