Script(s) for password policies

I have a fairly rigid set of rules to play by here and they can't be altered, which sucks of course.  We cannot set accounts to expire or lock them out.

What I need to script:

(1)Query AD for users whose passwords are 365 days old against the pwdlastset attribute.  I also need to be able to exclude accounts that are set to never expire
(2)Email a report of the number/list
(3)Email users in stages that their password is going to expire
(4)When the day arrives I need to scramble their password

I can generally do these separately fine enough but i would highly appreciate a powershell guru who could whip something up to help with this.  I can stumble through this but there is a bit of a time crunch on this.

Any help would greatly help.
