How to update zip data in mapping program (MapInfo 7)

This is as much a conceptual question as a MapInfo question. I have
MapInfo 7 and use the USZIPBDY.tab table to create thematic maps and
plot patients within zip code boundaries.

Our zip code files are old. I downloaded a file from ZipInfo.com
(ZIPList5 Geocode file). Then I looked at the table structure of
USZIPBDY.tab in mapinfo and created a file that contains the same
fields and field sizes. (Zip, St, St-fips, Cty1fips, Field 5; that
last field seems strange... hmmm.)

Anyway, we use a join which joins a list of zips with corresponding
count field (07006, 3) where the zip is first then the number of
patients who've visited in that zip code. The join matches that
table's zip with the uszipbdy table. When I use the original table
from mapinfo, the dots appear on my map. When I use my manufactured
table (in which I cut the FIPS provided in the file I bought into
ST-fips and Cty1Fips), the dots don't appear. I've attached the text
of the WOR file, in case any of you have experience interpreting that
info.

Anyway, my question is: How do the FIPS fields match to a location in
the US? And why isn't LAT/LONG required in the USZIPBDY file?
Shouldn't there be more fields for the software to be able to draw the
entire boundary of a zip code? And lastly, any idea why the dots don't
appear with my newly created boundary file?

Thanks in advance for any advice you can give me!
