Bill,
The front-most pin is the ground pin, and is the one that provides more
mechanical stability than any of the others - So if it is mechanical
stability you are after, re-solder all 8.
There is a tiny bit of looseness in the jack mounting to its grounding
lug due to the mechanical assembly of the jack itself. That is not
normally a problem even though it is bothersome to some. if it
maintains good electrical contact with the plug, you might want to leave
it alone.

It appears the front panel headphone jack on my K2 may be slightly loose.
I'd like to retouch the pins from the bottom side of the RF board without
removing the front panel. I can see 8 pins underneath J2 arranged as
follows:
front of RF board
--X--
XX-XX
-XXX-
rear of RF board
Should I retouch all 8 pins or just the first 5?
