If someone deleted object from OSM, and you do next mirror how would you know whether object was not yet there (so you must add it) or is already deleted (must not add, even check your own data). Solutions:
- track OSM changes or get also deleted objects. Not sure if possible.
- track your sync sessions, keep in memory that you have uploaded it once already.
Deletion here means any lost link: id tag removed or changed, duplicated etc. script should be able to find lost links and force to review all them manually.
Anyway, coming to the imports question (not dev), I'm not sure if OSM is really the place for specific businesses, which are not open for everyone so the data is useful for this service customers only. Perhaps just do mashup to your homepage. Mapnik will not render them for you anyway, and this is actually good for you : you probably want to show them as big interactive spots on map and not hardcoded to the base map. For the general community you are just "another big brand" here
