I kept the Party of Yosuke/Chie/Yukiko all the time I played the game, didn't bother leveling up all over again for the other characters :P
You don't need to replace Chie with Rise because Rise will take the place that Teddy had as being the main party helper ;) Her abilities are passive ones that will help you just as teddy helped you along the way.
I liked Setanta, but once you get to Strength Hanuman(level 42), you'll see a ton of all enemies physical attacks ;).
I didn't care too much about King Moron, kinda expected him to die :P You'll be surprised once you end the related search for his murdered ;)
