awk suggestion:

Code:
awk -v fields=8,10,16,17,22 -F' *= *|[ \t]*' '
  BEGIN {
    split(fields,F,/,/)
    for(i in F)
      C[F[i]]
  }

  {
    for(i=1; i<NF; i++)
      if(!(i in C))
        $(i+1)=0
    sub(/ /,"=")
    print
  }
' file

Another way in (gnu) sed:
Code:
echo "8,10,16,17,22" | sed 's/,/;/g;s/[0-9]\+/s\/[0-9]\\+\/A\&A\/&/g' | sed -f - -e 's/^\|$/ /g;:B;s/\([^A]\)[0-9]\+\([^A]\)/\1A0A\2/;tB;s/A//g;s/^ \| $//g' file

Regards.
