I'm not 100% sure I understand exactly what you want, so I'm going to be
extra careful; I apologize if it sounds like I'm talking down to you.

The short answer is to use relative paths: cd to where you want to
start, and tar from there. If that doesn't immediately answer your
question, read on.

Let's say your directory structure looks like this:


You want a tarball that contains 'dir3', 'dir3/file1', 'dir3/file2',
'dir3/dir4', and 'dir3/dir4/file3', right? If so, do this:

# cd /dir1/dir2
# tar czf /path/to/store/myfile.tgz dir3

If you instead want a tarball that contains 'file1', 'file2', 'dir4',
and 'dir4/file3', instead do this:

# cd /dir1/dir2/dir3
# tar czf /path/to/store/myfile.tgz *

You can do this all in one command with the -C parameter, but it's
easier to remember cd than how -C works (globbing gets more complicated,
-C works differently on different platforms/tars, and there's extra
stuff to worry about if you use it together with -T).

If you only want 'file1' and 'file2', and not 'dir4' or any of its
contents, do this (the 'n' means to not recurse into subdirectories):

# cd /dir1/dir2/dir3
# tar czfn /path/to/store/myfile.tgz *

If you want 'file1' and 'file2' and 'file3' but not 'dir4', there's no
simple way to do this. You'll have to do something like this (the 'h'
means to dereference symlinks and store the original file they point

# pushd `mktemp -dt tar`
# ln -s `find /dir1/dir2/dir3/` ./
# tar czfh /path/to/store/myfile.tgz *
# rm -rf `pwd`
# popd

This isn't perfect (it won't work if there are too many files, and if
any of the original files are symlinks they'll be dereferenced too--and
if you plan to do this more than once you'll be better off writing a
script that wraps this stuff up), but it should give you an idea.
