You should rejet. You won't see the true benefits of the K&N until you add an aftermarket exhaust, however.

you usually dont HAVE to but you SHOULD, now if you get a pipe or decide to run it with the airbox lid off then yes rejet is required or it will run lean.

I'd do it all at once so you don't have to jet twice.
