I thought that the XT thumbshifters had 6 clicks for 7 speed plus the extra 1 click for 8 speed compatability, Shimano knowing that it would be coming out. Believe it's the 9 speed where the spacing changes.

correct.
thumbies work spot on with an 8 speed cassette, its my gearing of choice.

Shimano 7, 8 and 9-speed all have different spacing:

The difference between 7 and 8 speed is only 0.2mm per cog, so if you set things up to work well in the middle of the block, your Shimano floating top jockey should take up the slack at the extremes.
Interesting that SunTour cassettes had two different spacings on the same block, something I didn't know. Probably why using their 8-speed thumbshifters with a Shimano mech works fine with both 7 and 8 speed SRAM / Shimano cassettes.
