I asked a similar question, but geared towards osmosis, some time ago on help:
http://help.openstreetmap.org/questions/4065/getting-specific-poi-data-and-keeping-them-up-to-date

I don't currently have read access to the part of my brain that holds
my memory of implementing Frederik's suggestions, but I will revisit
that as well.
Anyway, I thought it an interesting exercise to try and use this
toolset on a similar problem and gain some experience using the tools
mentioned here. They are very, very fast. Updating the US planet
extract with about a day's worth of changes takes ~3 minutes, the
filtering ~4 minutes (on an AMD Phenom 965 machine with 16GB RAM).
