multithreading

I have a number of threads that are performing a long runing task. These threads themselves have child threads that do further subdivisions of work. What is the best way for me to track the following:

How many total threads my process has created
What the state of each thread currently is
What part of my process each thread has currently got to

I want to do it in as efficient a way as possible and once threads finish, I don't want any references to them hanging around becasuse I need to be freeing up memory as early as possible.

Any advice?
