Hylas, you deserve a cookie for this post
I still have to watch the rest of the anime series as well, because it has not been released on DVD.
If you can, I suggest you to get the manga, which IMO is even better than the anime: the story is developed in a similar way, but a bit better, the characters are more interesting and some volumes of the manga are simply amazing. Also, you can read what comes next (after the point where the anime series stops) because Oda-sensei published, I think, 23 volumes of the manga.
I don't want to spoil everything but

I'm sure you'll love Chopper, the little reindeer. He's so terribly cute!
