searching desperately for module combination (permissions, hierarchy)

Hi!

I'm searching desperately for a Drupal module or module combination to fulfill the following requirements:
* hierarchical nodes
* grant permissions to single nodes for single users or user groups
* inherit permissions from the parent node

I tried a lot of modules but I could never fulfill all the requirements at once.

Just an example:
I give permissions to node 1 to user A and B. At the creation of child node 1-1 both users have automatically also access to that note because of inheritance of the permissions. I create another child node 1-2, to which both user would have permission, but I take away the permission from user B.

It would be cool if the hierarchical module would be supported by views.

Another case: I try to manage members of a club with drupal which is no problem. But what is the best way to also reference membership fees to them.
Example:
Member A is a member since 2008, so I want to attach 3 membership fees to him and mark 2 as payed and one as unpaid. Member B is a new member and I want to attach the membership fees for 2010 to him and mark as unpaid. To him I also want to attach a Sponsorship which he paid....
etc.

I think a simple way would be to attach child nodes to the users where every node is on membership fee. In the example it would be 4 nodes for the membership fees and one for the sponsoring.
Does anybody has a better idea?

I tried so many modules and combinations that I'm already confused.

Some of the modules I tried:
node hierarchy
content access
content permission
node reference
node relationships
nodeaccess
etc.

Many thanks in advance for your help!
