This statement returns the item displayed:
Outlook.AppointmentItem newItem =
(Outlook.AppointmentItem)msEventFolder.Items.Add(" IPM.Appointment.Event");
Therefore, you should be subscribing to the Write event of that newItem object. Note, however, that unless the user (or your code) changes an actual Outlook property, the item will not be saved and Write will not fire.
I had a hard time following the rest of your code logic, and it's not just because I read C# only a little. It looks to me like you are creating new appointments in FormRegionShowing and SaveAppointment rather than working with the item (newItem) that is already displayed.
In any case, if your only goal in using a form region is to get the user to enter data into OUtlook properties, I would strongly suggest that you build the region in Outlook's designer rather than VS2008's and save yourself a lot of coding time.

VS 2008 or VSTO 2005 SE? If 2008, did you create the region in the designer or import an .ofs file?
To create a new instance of a custom form programmatically, use the Add method on the target folder's Items collection:
newItem = targetFolder.Items.Add("IPM.Appointment.MS Event")
newItem.Display
If the target is a default folder, you can use the Namespace.GetDefaultFolder method to return it as a Folder object.

Also - I would like to put a "MS Event" commandbar on the content menu
when a user right clicks on the calendar - I have a commandbar
included there, however don't know what to put in the event handler to
make the new form region to appear...anyone got any thoughts?
The following works well:
newItem = targetFolder.Items.Add("IPM.Appointment.MS Event")
newItem.Display
and I hooked this up to my "New MS Event" on the right click content
menu.
However, when I select the "Save" on the ribbon for this item is never
saved to the calendar. When I select the "New MS Event" from the
Actions menu, the item gets saved to the calendar. Have I missed
something here...or is it another one of those Outlook dark secret
things 
Hey Sue & all,
Here is the code that handles the CommandBar event OnUpdate - this
function is in the ThisAddin.cs file:
/// summary
/// This function handles the click event of the "New MS
Event" button on the context menu.
/// /summary
/// param name="btn"/param
/// param name="cancel"/param
public void newButton_Click(Office.CommandBarButton btn, ref
bool cancel)
{
try
{
// get the MS Event calendar folder
Microsoft.Office.Interop.Outlook.MAPIFolder Calendar =
m_applicationObject.GetNamespace("MAPI").GetDefaul tFolder(Microsoft.Office.Interop.Outlook.OlDefault Folders.olFolderCalendar);
Outlook.MAPIFolder msEventFolder =
Calendar.Folders["MS Event"];
// creates a new IPM.Appointment.Event object to store
the form region content
Outlook.AppointmentItem newItem =
(Outlook.AppointmentItem)msEventFolder.Items.Add(" IPM.Appointment.Event");
// displays the MS Event region form
newItem.Display(false);
}
catch (Exception ex)
{
Utilities.Log.WriteToLog(m_EventLogName,
"newButton_Click() err: " + ex.Message,
System.Diagnostics.EventLogEntryType.Error);
}
}
so... I am getting the Calendar collections of folders and then
looking for the "MS Event" calendar folder. at that point I use the
code you suggested... it creates a MS Event form for me, however, on
the save (see code below in the MSEventRegion.cs file - I could not
find a "Save" event on the Outlook.AppointmentItem - so I used the
Item_Write event) it does not save the item to the MS Event calendar.
