Tutorial on how to connect with ESRI:

http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=How_to_work_with_WFS_using_ArcGIS_Desktop

The interoperability extension does not cost anything extra to install.

NOTE: If you’re using ESRI products you do NOT have to use WFS connect to our services!

See this blog post for instructions on how to connect without using WFS:

Our WFS services are OGC compliant and should work with anything that uses WFS such as MapServer, Gaia, uDig, QGIS and GRASS.
