Answer 1

It is not clear what are you trying to do. Based on expected results, something like:
  select  case
           when sup < 2 then elite
           else combined_str
          end elite,
          sub
    from  tableA a,
          tableB b
    where a.elite = b.freq_item
ELITE                      SUB
;1;10;2;3;4;5;7;8            2
;2;3;4;5;8;9;10              2
