It is a standard 3-clause BSD license. The "All rights reserved" portion definitely adds ambiguity (and only exists in the BSD license out of all major OSS licenses). There is StackExchange answer that goes into the history of it[1].
Copyrights are appropriate, they make it explicit who produced the work and make it easier to enforce the license. This license follows the general form of the BSD-style license [1].
