Thanks

Yes. The former is the wire protocol version, e.g. request/response serialization/deserialization. The latter is for the query language itself, e.g. syntax of the SELECT statement.
>> - Cassandra 2.0.x supports CQL 3 ?
Yes, starting with Cassandra 1.2 all versions support CQL3. In general, when someone is talking about CQL, they refer to CQL3.

Yes, Cassandra 2.0.x uses binary (also called native) protocol v2 while Cassandra 2.1.x - v3. All versions of Cassandra support previous versions of the native protocol.
