To have just the 002's don't use the -v option to grep.
i.e.
grep '.\{44\}002.*' infile > outfile2
So we've got
grep '.\{44\}002.*' infile > 002s_only
grep -v '.\{44\}002.*' infile > everything_else
I'd suggest you have a read through the grep manual page, also "man 7 regex" on Linux, "man 5 regexp" on HP-UX (not too sure about Solaris) will give info on Regular Expressions. (else there's always google!).
Study regular expressions. If you intend to work at the Unix command line, they will prove invaluable.

zgrep
ZGREP(1) General Commands Manual ZGREP(1)
NAME
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.
