Ok, new at playing piano and need help, please.?

Ok, so I want to learn to "read" sheet music. I like playing clical piano music and I think clical music has different notes b/c of the cleffs(?) I like Beethoven's Pathetic and Moonlight Sonata's and would be cool if I could just read the sheets and play. Anyways, I would like to play movement 2 of moonlight sonata (mvt.1 is overplayed, I think.) and Pathetic mvt.3 is one of my favorites. Is there a website where theres the notes to clical music or the two I mentioned (notes that correspond to clical music?) Anyways, thanks for everybody that answers my question.
