Hello! I can answer both of these questions for you. In the first question, ".... All information taken from you is useful." is correct, but so is "... all information that has been taken from you is useful." However, they would be used situationaly and the exact difference is somewhat arbitrary. For example, I might say the first sentence as a comment rather than a direct statement. Say I am talking to someone about a paper that I wrote and they ask if the information they gave me was "useful" I might say delightedly, "all information taken from you is useful." But, in a separate situation they may ask directly "was this information useful to you?" and then I would respond, "All the information that has been taken from you is/was useful." So you see, its really up to the feel of the conversation. Otherwise both are correct. As for the second question, "I don't know the location to the restaurant either do he" this is wrong and can never be correct English. The verb "to do" must agree with its subject "he" so it must be conjugated as "does". Furthermore, when you speak in the negative sense, "don't" in this case, the adjective "either" must be in the negative form : "neither" so it would be written as : "I don't know the location to the restaurant, neither does he." Hope that helps!
