I view Graphmate and Keymate as essential addons to do animation in DAZ Studio. AniMate2 is very useful also, especially if you want to use some aniblocks in your animation. I have AniMate2, so I'm a little vague on the difference between the free AniMate Lite and AniMate 2. I might be fine with just AniMate Lite, but definitely need Graphmate and KeyMate to do animation.
