SQL Server Failover Cluster Questions

Question

Dear All,
            I am building a two-node failover cluster on SQL Server 2012 SP1 (inside Hyper-V as a Guest Cluster) and want clarification on few things that I am facing.
1.  I am receiving MSDTC Warning.  I can go ahead and create the cluster, but want to understand whether this MSDTC is to be configured as a role on the cluster or not.  I plan to run SCVMM, SCOM, Orchestrator and Windows Azure Pack Databases
and Reports through it so in such a scenario, do I need MSDTC? If yes, how much should be the size of the MSDTC Drive? Is following process correct?
http://www.sqlnotebook.info/configure-msdtc-on-windows-cluster-2012/
2.  During First Node configuration, one needs to provide the "SQL CLUSTER RESEOURCE GROUP NAME".  Does it have any bearing on how it will be accessed by other servers for databases and logs? or is it just how the cluster resource group
would be named? would it be required for every instance that is created inside the cluster? Just to be clear, so one can name it according to the instance name.
3.  During the instance creation, one needs to provide "SQL Server Network Name".  As stated above, I plan to run SCVMM, SCOM, Orchestrator and Windows Azure Pack Databases and Reports through it, so would I be required to provide this
for all instances that I create or this is only required once in the cluster:
4.  During the instance creation, one needs to provide the features required for installation i.e. instance features and shared features.  As stated above, I plan to run SCVMM, SCOM, Orchestrator and Windows Azure Pack Databases and Reports through
it, so which features should be selected? so that there is less workload on the server.
5.  All the instances use TempDB for databases that are present inside it.  What would be the best practice with respect to TempDB.  One TempDB for all instance on the servers on a separate LUN or all instance having their own TempDB LUN?  What
should be the ideal size of the TempDB LUN?
6.  Should all the disks required for DBs and Logs be added to Cluster?  Should they be added normal disks or CSV Volumes?
Thanks in advance.

Hello,
 1.You can run the Microsoft Distributed Transaction Coordinator service (MSDTC) as a clustered resource on a failover cluster server for increased reliability, based on the failover capabilities of the clustered servers. You can
refer to the MSDTC section of the following blog about determine whether the Microsoft Distributed Transaction Coordinator (MSDTC) cluster resource must be created.
Reference:http://msdn.microsoft.com/en-us/library/ms189910.aspx#MSDTC
2. The Cluster Resource Group is where SQL Server failover cluster resource will be placed. Each clustered SQL Server will belong to a Failover
Cluster Resource Group. For example, if you had configure a two node SQL Server Cluster, each clustered instance on the two node belong to a same Cluster Resource Group.
You can change the Cluster Resource Group name, but notes the following name is reserved and already used as Resource Group names: Available Storage, Cluster Group.
3. Each SQL Server cluster is assigned a virtual Network name and IP address, which client applications use to connect to the clustered SQL Server.
4. Not familiar with SCVMM, SCOM, Orchestrator, but you should install the Database Engine Services and SQL Server Management tools.If you want to use SQL Server Reporting Services, you can install Reporting Servers, but Report Server service cannot participate
in a failover cluster.
5. You can use isolated disk for user database and temp DB of each SQL Server Cluster
6. Yes. You should use Cluster Disks which add to Clustered Shared Volumes to host the data file and log of databases.
