The simple answer to question 1 is no. Once a user posts a written review then you have the power to reply to the review. Everyone will be able to see your reply.
As for question 2, Google does not like the use of keywords. It is best to write a very detailed description of your application. The description is part of the search results. Try not to use names of other apps in your description because I have seen Google treat that as using keywords. As people find your app and install it, the app will move up the search results.
