comment NFS client requests file one at a time when listing directory
I am afraid, the metadata operations with any network file system is a pain over high latency connections. But I am not a samba expert.

comment NFS client requests file one at a time when listing directory
nfs4 can't help here. on high latency connections, try more aggressive caching options: check acregmax and acdirmax mount options.

comment Single process blocks NFS mount on entire node
Linux's nfs client uses only a single connection to the server and doesn't send a new request as long as reply for last one not arrived. You can try to mount with smaller rsize/wsize and and shorter timeout.

comment Linux NFS - set default user for new files on nfs share
If you want to see the same files uid/gids on client and server, then client ans server must use the same uids and gids or the same names for users and groups. In once case you need ud based mapping, in another - principal based.

comment Linux NFS - set default user for new files on nfs share
latest kernels in RHEL6 use numeric values over the wire instead of strings. To change the behavior you need to "echo N > /sys/module/nfs/parameters/nfs4_disable_idmapping" and clean idmap change with "nfsidmap -c"

comment Cloning a server across architectures
@Hammand in best case, you will get the list of installed packages. All you configurations made by hand will be lost. Follow suggestion from EEAA and use something like puppet or chef to avoid the same pain in the future.
