What I'd really like to have is the ability to define a picklist rather than an Auto-Number or a text field as the Name/ID field of a custom object. Since this currently isn't possible, the next best way is to intercept the "New Record" event, offer a page that provides the desired picklist and then populate the Name/ID field in the object's Edit page with the selected value.
Here are my problems:
(1) does anybody have a code snippet for creating such a page and populating a picklist with a list of values?
(2) does anybody know of a way to pre-populate a read-only (!) field with a customized URL? Populating an editable field in Edit mode is fairly easy, but I just can't figure this out if the field is defined as read-only on the page layout.
Any help is appreciated.

I have the following VF page.

<apex:page id="AddServiceCallTask" standardController="Service_Call_Task__c" extensions="extServiceCallTask">
    <apex:form >
      <apex:pageBlock title="New Service Call Task" mode="edit">
            <apex:pageBlockButtons >
                <apex:commandButton value="Save" action="{!save}"/>
            <apex:pageBlockSection title="Service Call Task Information">
                <apex:inputField ID="ServiceCallNumber" value="{!Service_Call_Task__c.Service_Call__c}">{!strSCN}</apex:inputField>

 And the following extension

public class extServiceCallTask {

    public string strSCN {get;set;}

    public extServiceCallTask(ApexPages.StandardController controller) {
        PageReference pageRef = ApexPages.currentPage();
        Map<String, String> pageParameters = pageRef.getParameters();
        strSCN = pageParameters.get('SCN');

The extension outputs the parameter ( {!strSCN} ) underneath the inputfield (under the part where a value would be typed)  instead of setting it as the default value for the field.  The inputField references a lookup field.

There are several places where I need to use this functionality.  What am I doing wrong?

I created a picklist field with three values - One, Two and Three. I set One to be the Default.
When I display the picklist field on a visualforce page using inputfield, the drop-down list shows --None-- as the initial item.
Am I missing something or shouldn't One be the default?
