Doing a user import, import will try to put the objects back where they came from if the tablespace exists and the user still has resource priv on the original tablespace. If not, then import will place the objects in the default tablespace (if the user has resource privs there). As long as the resources are set correctly, it doesn't matter if the original tablespace exists or not.
The catch-22 situation occurs when trying to do a full database import. In this case you are correct, import will put the objects back where they came from regardless of the defaults (this is primarily true because all of the resources, etc. are reset at the beginning of the import). In this case, if the tablespace the objects came from doesn't exist, it even recreates the tablespace 8-(, not fun if you don't have the required disk space still available.
