Answer 1

not sure if this is something that you want:
Create Or Replace Trigger deleteLD
  Before Delete on tablea
Declare
  vCtr          number := 0;
Begin
select count(*)
   into vCtr
   from all_tables
  where table_name = :new.tablename;
if vCtr > 0 then
   dbms_utility.exec_ddl_statement('drop table '||:new.table_name);
end if;
End;note: not tested
