OK, You've definitely sparked up the GAS (Gear Acquisition Syndrome) again! LOL Those are awesome photos! I just picked up the Fuji 60mm Macro, but haven't had a chance to play with it - already I like the looks of what you do with the Touit and want to look at more gadgets.
I have had pretty good luck with the extension tubes (11 & 16), I am hoping I can do as well with the Fuji 60 as you obviously do with the Touit.
