Actually it is quite simple.
You need the right BB for your BB shell threading (English or Italian)
Spindle length is all about ensuring the correct chain line (42mm chainline is standard, but there are variations)
The type of connection (square taper/ISO/JIS/octalink) is about making sure that the cranks can attach to the BB
