Either I don't understand the problem or you're making it too
complicated. <g>

You have a form to edit the properties.
...
<input type="text" name="last_name" value="&dtml-last_name;">
...

The action method of this form sets the REQUEST variables to the
property names:
...
<dtml-call "REQUEST.set('last_name', REQUEST['last_name'])">
...
(I generally use the same names for form vars and property names
to avoid confusing myself)

then:
<dtml-call "manage_changeProperties(REQUEST)">

Does this help?
