I think the best thing to do here is seek out to HR groups on LinkedIn, Facebook, and other social networking sites. There are many HR professionals who have lost their jobs or are looking to provide Remote HR services. Find somebody willing to help you with the immediate handover. I don't think the Manager, in this case can act the way he did. Cause there is a resource who will be taking over from where you've left. I understand your situation but it is your responsibility to not hamper the organization process and help them as much as you can for a smooth handover.
I agree that all the predefined situation that you stated shows a very bad management ethic, but you should always try to fulfill your end of the deal. if you can make a note of your issues and send it out to the senior management who you think is genuinely concerned with organizational culture (Founder/Director) etc. This is one of the main reasons why weekly employee pulse check have become such an important part of organizational processes.
The management gets a real and more in-depth picture of the employee perception about the employer, work culture, compensation/benefits etc.
