Blake has mostly covered it. But worth saying explicitly, if we assume that the best you're going to get on a GPS is 5m, but your concern is that you're mapping things that are much closer together - then the solution is to combine the GPS and paper based approach. The important thing from a navigation point of view is getting the relevant features correctly placed reactive to each other.
What you will find is that the combination of airial/gps and survey data will bring the accuracy down. But ultimately, relative postition is the key.
