The XP Pro CD should be bootable. The floppies are used in case you're installing XP on a non-bootble CD-ROM drive. (Rare, but it can happen). If you can boot from the CD, then don't worry about the floppies.... they won't have any additional files you need to install XP.
Floppy drives are becoming a thing of the past, but people still cling tenaciously to them. More and more computers are coming without them, and really... they are not needed anymore. The only thing I need one for is the F6 install storage driver part for my SATA controller. (I thought integrated SATA controllers didn't need extra drivers, but for some weird reason, mine does.) There is a way to integrate the drivers into the XP CD... I just have to find the engery to do it.
