[mrtg] MRTG, Cisco PIX, GETIF and OIDs

Having a confusing time figuring out some oids to query.  Got GetIF and the
relevant mibs from cisco's web site for my PIX 520 (ios 5.1).  Found 2
useful entries if anybody cares:
. = memory in use in bytes
. = free memory in bytes

I want to graph other things, most importantly connections, processor
utilization and nat xlates, if possible.  (I know there are perl scripts to
do this, but they require a telnet login, I only have SNMP read-only access)
I found the section:
onStatTable.cfwConnectionStatEntry (numeric .
under that are 5 entries; cfwConnectionStatService, ...StatType,
...StatDescription, ...StatCount, ...StatValue.  Service has 41 ENUMS (http,
ftp, ect.), StatType has 7 (in use, free, ect.)

How do I combine the service and the stat type to get the numbers I want to
graph?  Like say I want Webhttp(Service 12) Total open (type 2)?  I can't
seem to get any data out of GETIF when there are ENUMS that need to be

Any other OID's for xlates, processor util%, ect. would be greatly
