Help With New DIRECTV Coax Cable Network Configuration and Installation

We had hurricane damages that required a large amount of significant renovations. We are having a centralized network and patch panel installed for all of the communication systems in the house with new RG6. This will include adding proper coaxial keystone wall connectors in each room that will all feed back to the network panel. The network panel will then have the main incoming signal from the dish fed into the DIRECTV DSWM 30 SWiM Multiswitch. The Multiswitch has two SWiM output ports that will then have exactly two DIRECTV SWiM splitters (one off of each Multiswitch port for balancing the outputs) that will then be ran to each room. There will be a total of 12 coaxial wall connections, with a few rooms having more than one. The intent is for future expansion of service that would allow installation of one receiver per room. The multiple coaxial wall connections in a room is to allow for the convenience of connecting a receiver based on the room's configuration or furniture arrangement.

So, the questions are: 1. Is this configuration correct? I believe that it is based on all of the DIRECTV information and configuration guides I could find.  2. Did I overlook anything with the installation plan or are there any improvements that should be made to the configuration?  3. Since the Multiswitch requires its own power inserter, how do I handle any receivers that have a built in power inserter (such as the HR54 Series)? The Multiswitch requires a PI-29, so I believe the power inserter to the Multiswitch should handle the whole system power requirements within a single dwelling.  4. Do I need to have a DIRECTV SWiM splitter port connected to each coaxial wall connector individually or am I able to use something such as an Antronix or Holland balanced splitter to tie the individual room's coaxial wall connectors together on a single SWiM splitter port?
