In your first example below, using the "Get Term" web service call , it is intended to only provide information on direct super and subclasses.
However, if you would like to get ancestors of a term you can use the "Get paths to root/leaves"  web service call. For example to get parents of PR_000025533 (amyloid beta A4 protein (mouse)) use:
If you want to get inferred parent terms, then the inferred version of PRO needs to be loaded.
As far as the duplicate entries for 'is_a' and 'SuperClass', I believe that is an artifact of the underlying data representation and they do not have different meanings.
