Format partitions?

[Oldsmobile_Mike]

Re: full-fat formatting - I think it used to be frowned upon with some (SCSI?) drives as it could mess up the drive geometry - I doubt it's an issue on modern IDE/SATA drives - not much point unless you enjoy watching progress bars though

+1.  I think modern drives just ignore the command, anyway.

International Mode allows the directory to handle filenames with international characters (i.e. those not found in English, such as ä and ê.)

Personally I use PFS and wouldn't go back to FFS unless I had to (for example, if I was using a hard disk controller that didn't support PFS).  But changing your file system at this point is going to be a whole other can of worms you might not want to open, unless you want to start doing a lot more research on the subject.

while you do something like rebuild the engine in an Old's 442.

Been there, done that!
