Choosing the Right Outlet When Re-running Electric
You'll want to run 12-2 wire to accommodate the 20 amp breakers. And as far as the gfci outlets are concerned. You utilize them anytime your dealing with water, like in bathrooms kitchen sinks, laundry rooms, and exterior receptacles, as well as crawl spaces and basements below grade. You need to check with your local electric company to find out what the critical distance is for receptacle placement. In my area they need to be placed within 4' of sinks, and I can run 4 additinal outlets off the same gfci wiring. However, the nec codes may have changed, since I ran my electric. Your electric company will be able to tell you what you need to know. Just ask them to to let you talk to an inspector, and they'll tell you requirements for your local area. Some codes are locally regulated, while others are Nec controlled. Good Luck!
