I found some help setting this up from "Activating Home Sharing in i Tunes".
If you’re running i Tunes off another operating system, such as a Windows computer, you’ll need to manually set the i Tunes library to consolidate.

When she received her i Pad I created a new e-mail account and an i Tunes account specifically for her.
My problem now is that she has apps on her i Pod Touch and i Pad that were purchased with two different Apple IDs and she has to log-in and log-out to each one in order to update her apps as they were purchased with different IDs.
One is being used on my i Pad and the other on my Apple TV. Note the email address each time: sometimes it will be one, sometimes the alternate, depending on which account you used to purchase the app you’re about to update.
If not, are there hints about how I handle this situation in i Tunes on my i Mac?
However, keep in mind that even for “free” apps you should be cautious of any in-app purchases or subscriptions as these will generally not transfer to the new account either; consumable items like in-game “coins” will in some cases, but permanent upgrades or content downloads generally will not.(Please correct me if I'm wrong.) Is it possible to merge or consolidate two different Apple i Tunes Store accounts so we can share the apps and other purchases we've made?(We are married, so legally it is community property anyway!i Tunes is also the principal way to manage the music on Apple's popular i Pod digital audio player.The program is freely downloadable and is also supplied with Mac OS X as well as Apple's i Life home-application suite.Additionally, the program connects to the i Tunes Music Store which allows users to purchase digital music files that can be played by i Tunes.
