Nevermind, I figured it out. Don't know why it eluded me for so long.
Once the feature is created select it's attribute table with Application.Map.SelectionLayer.Records then you can add values to the specific fields.
One thing I'm not clear on is using Bookmark.
In this example:
Set objFeat = Application.Map.SelectionLayer.Records
objFeat.Bookmark = Application.Map.SelectionBookmark
objFeat.Fields("Field1").Value = now()
objFeat.Fields("Field2").Value = Applet.Forms("T1").Pages("Page1").Controls("C1").Value
objFeat.Update
Do I have to use the Bookmark property?
