Help reading naval muster rolls ww2

Question

So I found an interesting and relevant ww2 muster roll, including my grandfather, however there is also an interesting transfer from the 'printz' or prinz Eugen. However, the entire thing is using codes for various things, such as changes in rank or what have you. I cannot make heads or tails out of anything to the right of Column B.
See image attached.

James,

Reading across the columns starting at B:

Rating, which for Robert White is CTCA (Acting Chief Turret Captain).

Detaching command, in this case USS Prinz Eugen (IX-300), a captured German heavy cruiser. The cruiser sailed from the Baltic to the Pacific to become a part of the target array of Operation Crossroads at Bikini Atoll in July 1946.

Date reporting aboard current command (USS Alabama (BB-60),which in this case is 29 April 1946

Service number.

I hope you find this information useful.
