Help needed understanding controller extensions

Hi
 
I'm an advanced administrator but have absolutely no coding skills and am trying to teach myself some basic APEX and VisualForce.
I am having some difficulty understanding standard controller extensions and was hoping that someone can give me a little guidance here. I have scoured the discussion boards but have failed miserably in locating a post that I could understand so apologies in advance if this is a topic that has already been dealt with.
 
I'm trying to build a VF page that will allow users to mass update the Contacts on an Account e.g. phone numbers, flag as inactive etc.
 
My code:
 
public class accountContactList {
    public PageReference save() {
        return null;
    }

  public Account getAccount() {
    return [select id, name,
             (select id, name, firstName, lastName, title, phone, mobilePhone, email from Contacts limit 5)
             from Account where id =
             :ApexPages.currentPage().getParameters().get('Id') ];
}

public String getName() {
  return 'Account Contact List';
  }
}
 
My VF page:
<apex:page controller="accountContactList" tabStyle="Contact">

                       

    <apex:pageBlock title="Mass Edit Contacts">

                

 </apex:pageBlock>

 

 <apex:form >

  <apex:pageBlock >

   <apex:pageMessages /> 

    <apex:pageBlockButtons >

     <apex:commandButton action="{!save}" value="Save" id="theButton"/>

     

    </apex:pageBlockButtons>

    

    <apex:pageBlockTable value="{!account.Contacts}"

                         var="contact">

                         

      <apex:column value="{!contact.name}" width="25" />

      <apex:column headerValue="Title" width="100">

       <apex:inputField value="{!contact.title}"/>

      </apex:column>

       <apex:column headerValue="Phone" width="15">

       <apex:inputField value="{!contact.phone}"/>

      </apex:column>

       <apex:column headerValue="Mobile" width="15">

       <apex:inputField value="{!contact.mobilephone}"/>

      </apex:column>

      <apex:column headerValue="E-Mail" width="25">

       <apex:inputField value="{!contact.email}"/>

      </apex:column>

     

    </apex:pageBlockTable>

    </apex:pageBlock>

  </apex:form>

 

 </apex:page>
The above allows me to access and edit the Account's related Contact records but I am unable to save any changes I make
I have tried adding:
private final ApexPages.standardController the Controller
and
return theController.save();
to the Apex Class but without much success (as described in on p391 of the force.com Developer Guide that I picked up at Dreamforce '08)
Any help/guidance would be most appreciated.
Thanks in advance
