Creating a reoccurring WOL task.

I'd like to double check that I'm setting up a reoccurring Wake-On-LAN task correctly. Ideally I'd like to setup a WOL event for a specific time every week that will wake up all our computers so they can run virus scan (3rd party vscan software) before everyone comes in. I didn the following and would like to know if this is correct:

1. Go into Power Management.
   
2. Create a new power policy.
   
3. Add a power scheme that says: Turn on, Computer , Tue, 2 am
   
4. Save.
   
5. Right-click the power policy and select 'schedule remote wakeup'.
   
6. Go into the scheduled task and add the target computers.
   
7. Also in the scheduled task, turn OFF the 'Wake up devices - not applicable to unmanaged devices' checkbox on the 'target devices' section.
   

Here's what I'm unclear on:

1. will the power policy automatically kick off EVERY Tues, or do I need to set the scheduled task's schedule to reoccur weekly? Does setting the policy above as a scheduled task have the server send a WOL request every week, or does it send something to the client that the clien has to process every week?
   
2. What is the difference between clicking the 'schedule power policy' and 'schedule remote wakeup' options in step 5 above?
   

Just as a note to any LD employees, the power management section is really lacking in full documentation. The documentation doesn't cover scheduling the task, and doesn't cover the difference between 'schedule power policy' and 'schedule remote wakeup'. covering all the options would be helpful.
