What to use for adding syntax for hierarcical trees, metaclasses, tokenize.py or PLY?

You should look at the compiler package and at the new AST in Python
2.5.
For easy things tokenize could be enough, though. Notice that in Python
2.5 tokenize
grew a new 'untokenize' function which is pretty useful. See
http://docs.python.org/dev/lib/module-tokenize.html for examples.
