1) PROCOPT will have precedence at segment level. The one defined at database level gets overridden with the one at segment level. Hence the insert and all other update operations would work fine with the segment.
2)PSB creation and usage :- You can create a PSB but yet to use it, you need to do a PSB decode using IMS utilities. Also before using these self created PSBs, you need to check with your DBA whether you had provision to use them directly by your programs. Again this would be environment specific.
