If your system is at z/OS 1.7 or higher, you can exceed 4000 cylinders on a single volume by adding DSNTYPE=LARGE to your sortwork DDs and they will be allocated as large format datasets. If you don't code JCL sortworks and let DFSORT dynamically allocate the required sortwork space ( our recommended method), the sort work datasets are automatically allocated as large format.
For your other points, I'll take those under advisement with my team.
