Pool Sizing on a 5300
Given:
54 x 600 GB 15k in 8+1
16 x 3000 GB 7.2k in 6+2
Workload aside what would give you more raw performance? One big pool using all the disks. Or two smaller pools using 1/2 the disks.
This will sit behind 400 GB FAST Cache
Leaning towards two smaller pools, because that allow more opportunities to isolate workloads.

The attached White Paper provides information to help determine the performance for different configurations. Please see Chapter 5 (page 113).
More Pools are usually better if you have differing workloads and also to prevent a single failure domain. Some type of application also recommend using Raid Groups if you have Snapview Snapshots or Mirrorview / Async (processes that use Reserve LUNs). If performance is the main goal, Raid Groups also provide more consistent, reliable levels of performance (in my view).
