Do you have any pictures of the various bits and pieces that you could post up? Sometimes pretty small differences in thickness or tolerance can have a big impact.
How did the bleeding go? Were you able to get a constant stream of fluid with no bubbles? If not, then I'd definitely look into the clutch master cyl. If you were, and you said that you can see the clutch slave cyl moving the fork when you press the clutch, then that points towards some other fault. How much does the slave cyl move? At least an inch or so? If so, I'd tend to focus more on the clutch, pressure plate, clutch fork, or some other fault than on the hydraulics in this case. The fact that you said its moving but that there is basically no resistance makes me think that something in the stack-up between the clutch slave cyl and the pressure plate isn't correct. Bent clutch fork, incorrect throw-out bearing like you had said, or bad pressure plate seem like the likely contenders, although I guess its possible that the clutch slave itself is an incorrect part
Post up a picture of the trans input shaft, focusing on the smooth area that slides inside the pilot bearing in the end of the e-shaft, and on the splines that the clutch rides on.
Try pushing down all of the pressure plate teeth to make sure that you can see some movement of the friction surface inside the pressure plate. I'd look at each one individually, and then if you have a vice or hefty clamp, try to rig up something that would allow you to press them all to make sure the friction surface moves in the direction that would be away from the flywheel when the teeth are pressed towards the flywheel.
Inspect the clutch carefully, looking for scrapes, indentations, or other signs of damage. Its possible for something to have broken and jammed underneath the pressure plate, but it should have left a mark. Does the clutch slide freely along the splines of the trans input shaft? The clutch wasn't installed backwards, was it?
Does the pilot bearing in the hole in the end of the e-shaft look ok?
