Worth a look at django-treebeard as a tree library. I'm doing some work with it at the moment and I'm very impressed with it so far. It's pretty easy to separate the different data and connect to a tree- node object. IMO the api for tree work is good and all of the SQL complexity is hidden.
You can choose the storage method of the tree's [i.e. Adjacency Lists or Materialised Paths], with a common interface between the different methods - so in theory you can change them later.
