You know that the filename will be after the 7th field,
so you could do something like this:

Code:
gawk --posix 'NR > 2 && !/\/$/ {
  sub(/([^ \t]+[ \t]+){7}/,"")
  print
  }' infile

Which produces:

Code:
zsh-4.3.10[t]% cat infile
sms_snath_hp_C/CORE BUILD PREREQUISITE:
total 1556
drwxrwxrwx 2 sn sn 4096 2008-06-27 08:31 ./
drwxrwxrwx 13 sn sn 4096 2009-07-22 14:48 ../
-rwxrwxrwx 1 sn sn 15348 2007-05-11 08:37 This is a file name with seven spaces.jar*
-rwxrwxrwx 1 sn sn 22395 2007-05-11 08:37 This is a file    name with      eight spaces.jar*
-rwxrwxrwx 1 sn sn 73687 2007-05-11 08:37 ibmjcefw.jar*
-rwxrwxrwx 1 sn sn 767101 2007-05-11 08:37 ibmjceprovider.jar*
zsh-4.3.10[t]% gawk --posix 'NR > 2 && !/\/$/ {
  sub(/([^ \t]+[ \t]+){7}/,"")
  print
  }' infile
This is a file name with seven spaces.jar*
This is a file    name with      eight spaces.jar*
ibmjcefw.jar*
ibmjceprovider.jar*

If you don't want to modify the current record you can save it in a variable and then manipulate the saved record:

Code:
gawk --posix 'END {
  # print the filenames
  while (++i <= c) print fn[i]
  }
{
  # build an array to hold the filenames
  if (NR > 2 && !/\/$/) {
    rec = $0; sub(/([^ \t]+[ \t]+){7}/,"", rec)
    fn[++c] = rec
    }
  }' infile
