Headset and bottom bracket probably have the least difference in performance comparing mid grade parts to high end parts. You probably can't tell the difference between a cane creek s3 and a chris king when you're on the bike. Spend some of that leftover money on good tires and a good saddle that fits well. Those 2 things will make far more impact on ride quality than a BB and HS.
