As for whitewashing, well - I do trust documents, not opinions. And of course I would be glad if you'd refer to some facts and examples rather than to generalizations (as a matter of fact id does talk about 1991 opening of the Paneriai monument, and press review in 1991-1992 - not mentioning historiography at all: google search did mislead you on this one). 
Also you should note, that the book notes change in the press and the recognition of the problem 
Also you should note, that this books is 12 years out of a print and does not say a word about most recent research (This also leads to assumption, that information is more than 12 years old, since a book is not written in a day).  And Bubnys research is much more "fresh" in this respect, because it is published in 2003.
Well, about bias and creation of myths, we have to fight, there is a good read In there you can find also a comprehensive list of most recent Lithuanian historiography achievements in Holocaust research.
