Inspector & New Character

This will be my first murder mystery party and I am feeling slightly overwhelmed; although very impressed with how organised the pack is (I downloaded it so I could see it instantly and start giving out characters)
My first question is; does the Inspector need to be an outgoing person? Is he involved in the game as much as the other characters?
Is it very important to assign new characters to those that are murdered? I am just concerned that this will get confusing.
Thanks.
