Export/Import with where condition

Question

DearAll,
I am facing a problem in the delete of a huge table that take 3 hours
DELETE FROM HST HST
WHERE JV_TYPE <> 999
and ( HST.VALUE_DATE <= TO_DATE ('31/12/2010','DD/MM/YYYY')
AND HST.TRANS_DATE <= TO_DATE ('31/12/2010','DD/MM/YYYY'))
what i am trying to do is to export the HST table and import it into another table
but what i need to do is to have a dump with where condition including only the needed records in the table not deleted in the DML above as well as the indexes, triggers.
Thanks

If I try the following:
CONN / AS SYSDBA
CREATE OR REPLACE DIRECTORY dpump_dir1 AS '/folder/';
GRANT READ, WRITE ON DIRECTORY dpump_dir1 TO bokprod;
expdp bokprod/bokprod@uat TABLES=HST PARFILE=hst_query.par
In the parfile:
QUERY=hst:"WHERE JV_TYPE <>999 and ( HST.VALUE_DATE > TO_DATE ('31/12/2010','DD/MM/YYYY') AND HST.TRANS_DATE > TO_DATE ('31/12/2010','DD/MM/YYYY'))"
DUMPFILE=exp.dmp
DIRECTORY=dpump_dir1
LOGFILE=exp.log
impdp bokprod/bokprod@uat DIRECTORY=dpump_dir1 DUMPFILE=exp.dmp
TABLES=bokprod.hst REMAP_TABLE=bokprod.hst:hst_imported
My question is:
1- the parameter file, if i put it in the dpump_dir1 directory, is it read by the expdp command?
2- the hst_imported table created by the remap_table command , is it created with the indexes and triggers already existant on hst table?
Appreciate yoyr help Dears
