Dan,
Well since I last posted I found this site
http://www.defenselink.mil/multimedia/, its the official site and the photos are huge, in the search at top right type Boxer or Korea, then just hit next several times to scroll though the images, there in date order so your stuff will be near the end, there are some good Boxer images, the data seems to go back to Korea but there are some WWII images in there as well of Essex class carriers, most of the images have appeared at Nav source but these are not 800x600, there 3000x2400, excellent for details and modeling.
Heres aa link to the stern shot of Boxer in Korea

Regarding weapons, it looks like a lot of the 20mm were removed during the war, l'm aiming for 1951 as it gives me the best TF-77 options for my virtual set up, ie several WWII Essex candidates as well as Essex in SCB27A format, and interesting CA, CL and CLAA vessels. Some images I have from 53 show almost all the 20mm removed from the port side, certainly those midships went first, those on the bow catwalk lasting the longest, watch out for that extra platform added just aft of the port bow 20mm platfrom and in front of the 5" sponson, l'm not sure whays mouinted on there but it looks like some sort of antenna or new weapons training device, maybe for the 5" guns ?. You'll also need to remove the WWII style radio masts and fit whip antennas, also the Mk51 director tub between the bridge and #2 5"/38 turret needs to be removed.
Boxer does seem to have an extra 20mm starboard cat walk platform added, opposite the one where your father worked, but all Korean images I have show it devoid of weapons, yet the original starboard bow catwalk one retains its WWII 20mm fit.
Also, go here
http://www.history.navy.mil/branches/boxer.htm for Korea Boxer war reports, your father may well get mentioned or the missing weapons detailed, certainly the bow Quad loss should be in the minutes of one of the reports, the reports are usually quite detailed and l've got most of TF-77 vessel deployments for 1951 from these reports by reference and cross reference of each carrier and its deployments, I havent worked through the Escort carriers yet though.. If you like Korea and like Essex ships then these are a must, the full vessel list is here

Hope that helps a little more.
Best
