If I want to upgrade the firmware and ML, which should do first and how?
The system installs with Oracle 10g R2 and Baan V; and I notice these

1. vmstat -v | tail -5

35904 pending disk I/Os blocked with no pbuf
16449213 paging space I/Os blocked with no psbuf
2740 filesystem I/Os blocked with no fsbuf
83 client filesystem I/Os blocked with no fsbuf
6228 external pager filesystem I/Os blocked with no fsbuf

1. lsps -a

Page Space Physical Volume Volume Group Size %Used Active Auto Type
hd6 hdisk0 rootvg 6272MB 40 yes yes lv
pagingspace is around 35% and above all the time, even after business hours.

To upgrade the FW, it really depends on what you have exactly. You should
start here:
http://publib.boulder.ibm.com/infocenter/eserver/v1r3s/index.jsp?topic=/ipha5/fix_serv_firm_kick.htm
http://www-1.ibm.com/support/docview.wss?rs=0&q1=upgrade+firmware+p-series&uid=tss1fq115409&loc=en_US&cs=utf-8&cc=us&lang=en

For your "no *buf" errors, you should look at these URLs:
http://www-03.ibm.com/developerworks/blogs/page/aixpert?entry=tuning_jfs2_buffers_for_improved
http://www-941.haw.ibm.com/collaboration/ibmwiki/display/Wikip5/11Oct06+JFS2+Buffer+Tuning

Also, you might consider getting more memory if your budget allows.

Do the firmware first:

How - pick you machine type and model, 9113-550 and then read the Dasc doc for instructions.

ML / TL:
http://www-912.ibm.com/eserver/support/fixes/fcgui.jsp
Pick Unix, AIX, 5.3, Maint level or Tech Level and pick the one you want.

Select download, agree the licence, input your current level,(use oslevel -r or oslevel -s to find the current level on the system, download the files then use smitty updateall and make the input directory the one you downloaded the fixes to.
