If your wanting to format, easiest way is to use the actual windows 2000 disc(cdrom). Boot from it , choose delete partition, then create a partition and format using ntfs.
Or if your wanting to format by floppy would be make a windows 98 boot disc(floppy), load from it, delete partition, create new one, restart load from floppy again, then type format c: and hit enter and tell it Y when it asks are you sure.
As for using windows 2000 floppys I cant help as ive never used them.
