My 05 manual states 15/42. No need to change the ratio. Well I'm not going to.

Replacement sprocket ST3
I have seen a number of posts advocating going to a 42 tooth sprocket on the rear. If I do this, do I need to change the chain as well? Pros and cons of this mod? Any recommendations on the best source for a replacement sprocket?chain?
Thanks, Jack.
