Here's what I have done to add read/write capabilities to my NTFS drive:
$ sudo /etc/fstab
/dev/sda5 / ext3 noatime 1 1
/dev/sda7 /home ext3 noatime 1 2
/dev/cdrom /media/cdrom auto umask=0022,users,iocharset=utf8,noauto,ro,exec 0 0
/dev/sda1 /mnt/windows ntfs-3g rw,nls=utf8,umask=0222,uid=myuser,gid=myuser 0 0
none /proc proc defaults 0 0
/dev/sda6 swap swap defaults 0 0
where myuser is my actual Linux user name. That will restrict any other user to read-only access (umask=0222) but will give myuser ownership of the files in the mounted partition.
