There is a TIGER editing page at
http://wiki.openstreetmap.org/wiki/TIGER_fixup which is a good start. I'm
sure it can be improved.
Having edited connectivity errors across the US, I can say that the large
majority of fixes are obvious and simple. In general, (and I realize I'm
wandering into dangerous territory with this) the tougher fixes are in the
larger metro areas, where road networks are more complex and features
densities higher than in rural areas. If you're a newer editor there's a
large collection of simple unconnectedness across the US and, as your
skills improve, you can venture into the urban areas with more confidence.
A good Rule of Thumb is to simply skip it if you're not sure what you're
about to do is correct.
