Depends on your definition of comfort -- the bike will definitely handle better, meaning less effort and tension for you. The biggest thing you notice right away is less brake dive.
Don't wait on the rear shock -- get it rebuilt pronto, if not sooner. That will make a huge difference in handling, you won't bottom out over bumps, it will stop wallowing, and the bike will be FAR more pleasant to ride.
You may also want to replace the noodly stock handlebar with something stiffer -- I found that the stock handlebar's incessant flapping was extremely tiresome. A set of MSR ATV bars took care of that for around $25.
