1) Nobody will know why it leaks, you will have to diagnose this. Find where the fluid is leaking from, most shops could do it in 5 minutes.
2) Different splines I believe are for different input shafts, maybe someone can chime in there
3)I would replace every part of the clutch system that is cheap/important. Better off spending an extra $200 and know everything good to go. do it once or f*ck around and re do it all.
4,5,6) I would not do this yourself seeing as your asking such simple questions. If you dont know any answer to these questions seriously take it to a decent shop. Google is your friend!
