I have used CyberTracker (www.cybertracker.co.za) for datalogging in the field. This software (shareware) is designed for palm or pocket pc platforms and was designed specifically for GPS applications. Essentially, you can design a database or series of forms to collect the data that you need from each point. It can also record GPS locations. It is probably worth checking out, but you will have to still find appropriate hardware that meets your accuracy needs.
