So where does a spindle fit into all this?

Anyhow, back to my FSA crankset question... so here is an example: FSA K Force Light Carbon Compact 50 34 175mm Road Bike Crankset Ceramic MegaExo | eBay

Will that fit the Prologue? That particular set is too long of crank arms for me but just for example. It is Mega Exo and includes 68mm threaded standard english BB, that's all I need right?

Also for the Dura-Ace 7800 crankset I still need BB for my Tempo. I think all the current gen back to my 7800 all use 24mm Hollow Tech II or something like that and all Hollow Tech II BB are compatible correct? So I could use a brand new DA or Ultegra BB?
