It's in the same subforum stickied at the top.

In a nutshell:

26-44 (personally never got it run faster than 25-42 but whatever)
14" N but you can use 12.2" L if your gunners are not high enough level for them.
0.2" belt and as much bulge as reasonebly you can fit (you should go at least 40 OH in a kongo)
Depends. The standard crew fr IJN is 4 engies 4 repairers. You have 5 support slots so i guess you should go 2 engies 2 repairers and scout (and interchange them because you will need them on later BBs)
You also should use the T slots to level AA gunners (class them as armory sailors and wait with classing as DP gunners till they reach at least level 62) because high level IJN AA is one of the best... you can place some HH or lesser guns there in the meantime. 

Sure. Skip the Kongo.
