For what it is worth, there is a link about the Texans here which mentions the examples you already given and includes the use by the USAF as FAC in Korea. However, in the same paragraph about FAC use in Korea, it says:
"They were also flown for air rescues and leaflet-dropping missions. Several were used as interceptors against the North Koreans, who were flying Soviet-made Polikarpov PO-2 night raiders. "

Here is another article about night fighting in Korea with no mention of using Texans, so ?????...

I suspect if Texans were used they had no successes.
