yeah man, if you want to not be eternally clueless while using linux, you're going to have to start getting comfortable with the command line. forget about kde/gnome, to mount partitions at boot up, you need to edit /etc/fstab.
here is mine:
/dev/hda5 / ext3 defaults,errors=remount-ro 0 1
/dev/hda8 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto defaults,user,noauto 0 0
/dev/cdrom /cdrom iso9660 defaults,ro,user,noauto 0 0
/dev/hda9 /home ext3 defaults 0 2
/dev/hda7 /mnt/stuff vfat defaults,user,noauto 0 0
of course it looks like crap here because of the non-use of monospace fonts, but the last line should give you an idea of how you want it. you will want to change it a bit though, because i can only write to my vfat partition as root (actually, gotta look into that...i'm TOO lazy sometimes
)
update:
/dev/hda5 / ext3 defaults,errors=remount-ro 0 1
/dev/hda8 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto defaults,user,noauto 0 0
/dev/cdrom /cdrom iso9660 defaults,ro,user,noauto 0 0
/dev/hda9 /home ext3 defaults 0 2
/dev/hda7 /mnt/stuff vfat defaults,user,noauto,umask=000 0 0
that should make it r/w for users
