Your requirements are stated in a very confusing way and I see absolutely no need use grep. I don't write code using csh, but I think the following Korn shell script will do what you want. (It should also work with bash or any other shell that recognizes basic POSIX shell syntax.)
if [ $# -ne 2 ]
then    printf "Usage:\t%s list_file dest_dir\n" "$IAm" >&2
        printf "\t\$HOME/dest_dir must be an existing directory\n" >&2
        exit 1
if [ ! -f "$1" ]
then    printf "%s: \"%s\" is not a regular file\n" "$IAm" "$1" >&2
        exit 2
if [ ! -d ~/"$2" ]
then    printf "%s: \"%s\" is not a directory\n" "$IAm" ~/"$2" >&2
        exit 3
while read -r file
do      if ! cp "$file" ~/"$2/$file.bak"
        then    ec=4
done < "$1"
exit $ec

zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
