Exporting with your own tiles should be straight forward. Several of the
export formats use the Mapink Cairo renderer that was added about 6
months ago. You'll need a version of mapnik that includes these changes
and is compiled with the appropriate Cairo libraries available.

The search system uses another database which is held on
gazeteer.openstreetmap.org. I guess this should be OK for you though.

Yes but be aware that the API does not cover everything. For example all
the pages with user related information expect to query data in the
local database which isn't publicly accessible. You could start having
your own users registering locally but you won't be able to directly
access the information from the main site.
