If any of you are into historical fantasy fiction, a good author to read who uses the Templars as a backdrop for her stories is Katherine Kurtz. She wrote two books with Deborah Turner Harris called The Temple and the Stone and The Temple and the Crown which use the exact same questions in this thread as the plot. Being fantasy, of course, it incorporates magic and such. The two books take place just prior 1307 and the outlawing of the Templars. They help Bruce ascend the throne of Scotland with all kinds of mystical connections dealing with the Stone of Scone and the Templars, and fight an evil occultist in France who just happens to be William of Nogaret, who in the books and in real history was Philip's chief minister. Good stuff if you like historical fantasy novels.

Katherine Kurtz also edited three books short story fiction dealing with the Templars Tales of the Knights, On Crusade, More Tales of the Knights Templar and Crusade of Fire.
