Tomás y yo leemos unos libros. This is the right response becuase, the common action that people write; when it comes to books, is reading(leer). Also, you're talking in a plural form, becuase you are naming more than one person. That is becuase, it is leemos and not leer. To sum it up, the correct answer is leemos.
How are you today?, that is what it means.
Actually, the superlative form of "bonita" wouldn't be "bonitísima", it would merely be "muy bonita". Just like "very beautiful", not "beautifullest"
