The fdisk /mbr is a MSDOS command.  I think you mean the more modern command 
fixmbr and if you run this from a Recovery Console (using your WinXP 
installation CD) your computer will self-destruct in 3 seconds (only 
kidding! :) ) What either of these two commands do is write into the MBR the 
M$Windoze bootloader code.  Your Gentoo installation will thereafter be 
inaccessible without a LiveCD.  You can chainload grub from the WinXP 
ntldr.exe or you can reinstall grub in the MBR.  I would recommend the 
latter, unless you do not intend to keep the linux OS or its /boot partition 
on this machine.

Err, no it won't.  To restore grub boot using a LiveCD, or a Grub floppy and 
install grub as per the Gentoo handbook.
