Thread: Get info about a proccess

How can I get the following information on a proccess?:

CPU Usage
Memory Usage
Memory Usage Delta
USER Objects
Virtual Memory Size
Base Priority
Handle Count
Thread Count
Fiber Count
GDI Objects
I/O Reads
I/O Read Bytes
I/O Writes
I/O Write Bytes
Program Path

The Process Status API (PSAPI): http://msdn2.microsoft.com/en-gb/library/ms684884.aspx

Cool.

Is there a way I can obtain each induvidual handle in a process?
