Generally, unburned fuel getting into the converter is what damages them. How is it running?, what size engine? What did the dealer say is "wrong" with the converters they are replacing? -->You can easily damage your catalytic converter by making a lot of very short trips and not allowing you car to properly reach operating temperature.

How can I replace my catalytic converter?

First, lift your car using ramps to ensure that you can reach the converter which is located about midway down the length of your car. Second, remove all the bolts holding the converter in place. Third, make sure that the catalytic converter that you have purchased is right for your car to avoid any confusion. Fourth, take your O2 wrench and remove the O2 sensor before you unbolt the catalytic converter. After that, remove the pipe that connects the sensor to the converter. Fifth, bolt the new catalytic converter in place after you have taken out the old one. Sixth, re-attach the exhaust pipes and O2 sensor. After this is done you are basically done!

For 2001 VW New Beetle-replaced catalytic converter in June 2008. Did not pass inspection in December of 09 because code showed that it needed a catalyst. How long should a catalytic converter last?

It depends on what kind of converter you purchased. If you purchased a cheap aftermarket converter, then I'd guess it wouldn't last as long as an O.E. Volkswagen one. I'm guessing that your original one lasted seven years, so I'd think that a new one should last that long. It's possible that another problem such as a bad fuel injector or a miss in the engine could cause the engine to dump raw fuel into the converter. This would considerably shorten the life of the converter. A vacuum leak could cause the same problem. It should last more that a year and a half, either way, although it's doubtful that the part will be warranted longer than that.
