I get ~7800 RPM at 60mph, 62 mph (100 km/h) gets me about 8000 or so. I have the 17T front sprocket. It's great if you want to lower RPMs at high speed, but do beware if you live in hilly areas/mountains, because you do give up a bit of low end torque. I like it overall but I felt it earlier this summer riding some mountain roads.

Is there a need to change out the chain?

No need to change the chain to install the 17 tooth sprocket, there is enough adjustment compensation to accommodate the difference.
To install my 35 tooth rear sprocket I had to remove 4 links.

The 35 tooth rear gives you a little more "overdrive" than the 17 tooth front.

I guarantee you will  love the 17 tooth once you've ridden it a time or two.

It will take you about 15 mins to swap the 17 for the 16  ;)

Yes, it's pretty easy. I spent way more time finding and buying the appropriate wrench to get the axle locknut off than actually changing the sprocket :)

One thing I will add is that it's conventional wisdom to change your chain and sprockets all at the same time to even out wear or to prevent premature wear. In the case of the front sprocket it's probably not as big of a deal, and even less so if you're doing it in early in the bike's lifespan, but just a word of caution.

I did the 17t replacement and I weigh about 125lbs.  I really appreciated the drop in rpms on my 50+ mile commutes every day and even though now I only travel about 20+ a day, I still prefer the feel.  Full throttle with the wind at my back and a little drafting and it's possible to get the bike up over 75mph and on the verge of redlining, but I've only done that on a handful of occasions and only when I was feeling particularly crazy.   :P
