You don't want to send player input to the server. What you probably want to do is send an abstracted representation of what the player wants to do to the server, and then run the logic on there.
Likewise you don't necessarily want to send back everything the client needs to do. For example, you can send some kind of message saying "NPC X died", and the client determines what animation/sounds to play. Stuff like that.
The trick is to find the line where bandwidth and processing power (on the server) is trumped by preventing people from cheating. Usually you make any kind of game-changing authoritative decision on the server only, and leave all the ancillary visual stuff to the client.
There are a lot of more specific questions on this topic all over the site. For example:
Should collision detection be done server-side or cooperatively between client/server? Should collision detection be done server-side or cooperatively between client/server?
Who does the AI calculations in an MMO? Who does the AI calculations in an MMO?
Should the game host be the authority, or another dumb client? Should the game host be the authority, or another dumb client?
