System tuning recommendations

Some of our counterparts in other divisions managing AS400's have commented
negatively
on our pool size allocation, and also against using IBM's QPRFADJ set to 3
(they prefer 0).
Our system is primarily green screen rpg/db2 stuff, fairly straightforward.
We have about
200 open interactive sessions on a typical day. Our interactive CPW is 70.

My question is - do any of you all have any recommendations for system
tuning given our application?

Here is a snapshot of our wrksyssts:
