I think I'll join you in the exploration. I have a TS-E 24L that I have hardly used.
To me, the architypical T&S shot is an interesting rock formation at your feet, dominating the foreground, with a magnificent mountain behind it. I may have stumbled across a nice location this evening, with the rocks on the shore near West Kilbride and the mountains of Arran in the distance. I'll see what I can do.
Getting the focus right is >very< difficult. I use live view at maximum pixel-peeping setting and wander round the image checking the focus. As you say, there are three dimension to play with - the tilt, the which varies the angle of the focal plane, the shift, which moves the focal plane away from the centre and the focus ring, which moves the plane further away or closer. Move one and you need to adjust the other two to compensate...
To start with, budget an hour for setting up a shot. And if you haven't got a tripod, and time in HK, it isn't the place to start
Once you have the hang of the technology, I am very interested to see how you use it an apply it.
Of course, it is something that won't be appreciated in small images on the 'net. But it will really come into it's own, when you can print out all that detail on your lovely large format printers...
