A few qualms with your assumptions.

First, I agree that Mr. Bennet is very self-centered and irresponsible, mainly indulging in what he wants, needs and likes.
Mr. Bennet never signed any entail; it was set in place by an ancestor long before Mr. Bennet could have had any say in the matter. Without a son to co-sign a document to break the entail, he had no hope of doing that either.
Do we know that Mr. Bennet has not been setting money aside for his daughters? With five daughters, he would have to set aside a lot of his two thousand a year each year to provide them anything close to Augusta Hawkins's dowry in Emma, much less something along the lines of the Bingley sisters.
I don't see any evidence that Mr. Bennet was reluctant to visit Bingley, only that he was reluctant to admit to Mrs. Bennet that the visit had taken place.
Mr. Bennet was among the earliest of those who waited on Mr. Bingley. He had always intended to visit him, though to the last always assuring his wife that he should not go.... (Ch. 2)
We have no information that Mr. Bennet was not on a good footing with his in-laws the Phillips and the Gardiners.
I agree that Mr. Bennet did not take his daughters for a season in London, nor did he take as active a role in his local community as he could (the early visit to Bingley notwithstanding); and I have said, I agree with your overall summation of Mr. Bennet's character flaws.
