According to the Apache 2.0 docs the location directive only works within the following contexts: server config, virtual host. Both of those exist in the server config files. Unless you have a REALLY friendly server admin, you're not going to get access to those configuration files.
Unfortunately, it doesn't look like you're going to be able to do too much with your hosting account. All is not lost, however. If you can find an old box to beat on you'll learn quite a bit more by installing and configuring everything yourself (I sure did!).
