If the documents aren't sufficient in whole I'd recommend posting each of these questions individually on here unless you're working with our sales and services organization in a jumpstart program to answer some of these technical details.
I'd look at network profiles on the host reservation level which allows you to set the network settings on a cluster.
As far as storage DRS, support for SDRS is not generally available. Storages is directly provisioned to datastores, you can choose to reserve a subset of availble stores and prioritize them. In addition there is a storage policy so you can group these.
Templates usually are a subset of clones, for example WinXPLarge, WinXPSmall, WinXPApproval, etc, these all use the same template but have different business rules and customization after clone.
HA and DRS should be in the the reference architecture and install that is published. Usually all sites go behind web farms, databases clustered, the only consideration is that there is a service that cannot be active/active configuration so there has to be a failover procedure. There are plans to resolve this which requires concurrency planning testing.
