Edit /etc/fstab , and create a mount point, finally you link the mount point directory to your /home/user/ directory.
This may work for you:
/dev/hda2 /mnt/win_share vfat rw,auto,umask=0000,users,exec 0 0
It will give you access to your shared fat32 drive, make sure you create the /mnt/win_share directory or however you want to name it.
The linking part is easy to do in a Windows Manager, for example kde or gnome.
