You're probably not going to have much luck because tar.gz archives don't have a separate table-of-contents, but rather are just streamed one after the other with a header prepended (just like it was being written to, erm, tape; go figure . . .). On top of that, the entire archive is compressed, so in order to get to a file in the middle you've got to read along and uncompress until you find the file in the archive you're interested in.

The easiest thing (if you can wrangle it and want to avoid unnecessary overhead) would be to get whomever's providing you the file to switch to another format (e.g. zip) which has a separate index and individual parts can be easily extracted piecemeal.
