Answer 1

impdp system/manager@orcl file=file name(.dmp) full=y show=y log=show.logimpdp ? Is it a typo ? If not, then you can't use impdp to import an 8.1.7 export file, you have to use imp command.
To set NLS_LANG environment variable you can do :
SYS@db102 SQL> select * from nls_database_parameters
  2  where parameter in ('NLS_LANGUAGE', 'NLS_TERRITORY', 'NLS_CHARACTERSET');
PARAMETER                      VALUE
NLS_LANGUAGE                   AMERICAN
NLS_TERRITORY                  AMERICA
NLS_CHARACTERSET               WE8ISO8859P15
SYS@db102 SQL>                                                                   then, at OS level, before importing
$ export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P15
change values with yours.
