I know that this isn't the full answer you are looking for but...

man ps

There are some great examples in there.

Try the different flags.  If you want all users at first, then the 'ux' 
flags.

I use ps aux when checking processes.  At least I get a list of all 
processes and users.

I have found that mixing flags has some strange effects at times.
