I am trying to create a VF page where I show all contacts related to an account.  Once the contacted is selected and the user presses go, I want to display the name of the contact.  I can get it to display the id, but I can't figure out how to access the other contact fields.  Does this have to do with returning the contact id as a string?  Can I return the id as a contact?  I have been trying to do this for a while, and I can't figure it out.  I have also read through a ton of docs, but can only make it work when multiselect = true.  I want to do this when multiselect = false. 

Here is my code. 

Thanks for your help.

Apex Page:

<apex:page controller="newOpportunityController" tabStyle="Opportunity">
  <apex:pageMessages id="msgs"/>
  <apex:sectionHeader title="New Customer Quick Quote" subtitle="Step 1 of 3"/>
    <apex:form >
      <apex:pageBlock title="Customer Information" mode="edit">
      <apex:pageBlockSection title="Account Information">
                        
        <!-- Within a pageBlockSection, inputFields always display with their
             corresponding output label. -->  
              You are viewing the {!account.name} account. <p/>
      </apex:pageBlockSection>
      <apex:pageBlockSection title="Contacts">
         <apex:selectList value="{!selectedContact}" multiselect="false">
            <apex:selectOptions value="{!contact}"/>
         </apex:selectList>
      </apex:pageBlockSection>
    </apex:pageBlock>
    <apex:commandButton value="Go" action="{!test}" rerender="out, msgs" status="status"/>
