    AFAIK, There is no need to replicate / share following three location with EV2 in DR site.  

    - msmq
    - index metadata
    - ev temp

    Answers for following two location.

    - ev cache :- No need to replicate but location must be same (ex 'd:\evcache' should be same in primary & DR server).
    - ev storage queue:- It's should be on shared location that is accessible for both servers (ex '\\server\StorageQueue' location to be set in the properties of both the servers).

    Following Tech note will help you know additional requirement for building block configuration.

    I will also recommend to keep EV in backup mode during failover time due to one of the known issue listed in TN http://www.symantec.com/docs/TECH231820

    Recommendation for Building block with MSCS is mentioned in TN  http://www.symantec.com/docs/TECH215320
