The plate orientation I'd feel should be all the same way for the steels, both in front of the double and behind. To me it looks like your front set are correct and you should switch the behind one's to match.
My perception of the reason why is; when the clutch is driving the steel's lugs would be hard up against the clutch hub splines, so to slide the hub through them it would be advantageous to have the "non sharp" side of the plate arranged so that it can't hang up on the aluminium as it is moved with the lever. It'll set it's own position more easily coming back under spring pressure as the plates are effectively floating without drive on them or the opposite affect dependant on how they are mounted.
Spring length, you seem to have F2 springs as they meet that spec. They shouldn't in any way damage the lift plate.
The lift plate damage usually occurs when the four bolts are torqued with something misaligned at the back of the clutch pack. I've seen it assembled with two long bolts screwed into two of the holes and used as handles to jiggle the assembly, making sure it's all in place prior two putting the other two correct bolts in to get and check location. Then, remove the long "handle" bolts, fitting correct one's, and final tightening to reduce this risk.
