Here is what I could determine by a quick research.
The goals are listed in a book: "THe Naked Communist" by W. Cleon Skousen, who was a senior FBI agent under J. Edgar Hoover, the police chief of Salt Lake City, Utah, and a full professor at Brigham Young University.
Florida Congressman A.S. Herlong Jr. entered this list into the Congressional Records in 1963.

I don't know where Skousen got his list, he may mention it in his book. Considering, that he was an FBI agent, maybe they got hold of some commie documents.
But I have read elsewhere, that the communists were working hard on destroying the capitalist countries, starting with the US, "from within". It was a major strategy for them, so it's quite possible they outlined those items.
It is also interesting that those goals first saw the light of day in 1958, before a lot of them have been accomplished, that now are totally accepted, so it's not as if someone looked around today and created the goals retroactively, to fit today's status.
As I said in my previous post, those are secondary documents. I know of many great historians I respect but I would expect that each and every one of them back up any controversial claims or statements with primary documents. The Congressional Record, btw, is not a good source. Every wacko, including Maxine Waters, etc., can insert whatever they want in that. Again, this wording sounds like something out of Dr. Evil. Where does it come from?
Speaking of that, a couple other items I should add. The FBI seized some internal Communist documents from a meeting in Bridgman, Michigan in 1922; these are cited in R.M. Whitney's 1924 book Reds in America, which has been reprinted a few times. Also, CP papers such as The Daily Worker are available in microfilm collection:
Newspapers of the American Communist Party
A virtually complete set of the official newspapers of the American Communist Party from 1919 through today’s editions is now available. The retrospective set includes People’s Daily World and its predecessors—The Daily Worker, The Ohio Socialist, The Toiler, The Worker, The Midweek Worker, and The Southern Worker. An annual subscription to People’s Weekly World (two reels annually) keeps coverage current.
A portion of the FBI's files on The Daily Worker are on the FBI's FOIA site and on CD-ROM:
