I have returned to this posting to update the entry.
My "work person" came to my home on 8-27-2009 bringing along a generic ballcock that he put into the tank in the large bathroom. Several days later I was aware of the "ghost flushing" - I went to press gently to the left side of the ballcock - and stayed to monitor the activity - I could see the water level in the tank increasing - that worked (I have not noted a problem in that area since.)
The commode in my bedroom bath turned out to be a more difficult problem.
Somewhere along the line I had found the website
FAMOUS PLUMBINGSUPPLY dot COM the largest award winning plumbing, kitchen and bath Internet catalog since 1995 provides great service. We have the largest selection of plumbing products and supplies on the net with 2,546 pages of a complete plumbing .
The problem: to identify the model number of the Eljer toilet that had been put in place in 1974. The webside

We have the largest selection of plumbing products and supplies on the net with 2,546 pages of a complete plumbing had a section showing photos of the many Eljer toilets - not there.
When my "work person" was here on 8-27-2009 I did see a number 2152B imprinted inside the tank. We went to the Plumbing Supply website and somehow (I did not write down the manner) - we found what I will refer to as a listing of generic parts.
I ordered two "Radiator Specialty B-254 Tite Seal Tank Ball" units. My thoughts - not all that costly and if they worked it would provide me with a "backup" item. I placed the order on 8-27-2009 at 11:00AM and the package arrived via Priority Mail on 8-29-2009. (California to Pennsylvania in two days - remarkable!)
My "work person" returned on 8-31-2009 and put the new ballcock in the bedroom commode. He did tell me that he would expect that I would have problems with the ballcock settling "in place" for awhile. I did experience "ghost flushing" off and on - I went to gently touch the left side of the ballcock and that would solve the problem. Sept 5th was the last time I had made a notation concerning "ghost flushing".
I honestly feel that the above noted activity along with what I had noted in the 9-20-2009 update on my posting "Need Plumbing Advice" has resolved my current plumbing problems.
Even with "Pushkins" parting shot on that posting - I want to thank the contributors for their kind assistance. I truly do feel the problems have been resolved.
