My guess is to set ownership to "user" and specify read-write. Here's a line from my /etc/fstab for a partition on my external. I can manipulate files on it just fine:
UUID=1655a198-15a7-471f-9e99-e3fc9fd92ca0 /media/sdb1 ext3 rw,user,auto 0 1
Also, if you are using the UUID, I don't think you need the /dev/
item with syntax like that above.
Just as a quibble, it might be worth considering mounting it to /media or /mnt, then symlinking the relevant directories from /home/[username]
