Hardwood Floor Nailer
Here is my suggestion of how you should install the floor:
Square up your room. Get your first run installed (take your time and align it right.. the rest of the room depends on the first run), predrill your holes, nail finishing nails in by hand and punch for the first run. Once this run is in place then go get your compressor and nailer this will save you about 2 or 3 hours in preperation work (I find the longest part is setting the straight line on the first edge... and all sides if you are doing boarder work). Now you can run the entire room none stop. To save even more time get another person or two to sort the wood out for the person doing the nailing remember your overlaps, and a little verification that you are not putting some very different colors together (basically orginize the wood for the nailer). They say that you can lay 450sf a day with a phenmatic if you know what you are doing (based on 2.25" wood).
Just my thoughts.
