About the earrings:
They use bones for movement, and are under the head bone in the earrings figure. Both the hooks and the ribbons may be rotated however you need to follow gravity, also the hooks can be translated if you wish to put them on a different figure other than Genesis 2 Female, in that case parent them to the head rather than conforming (Fit-to). When using on Genesis 2 Female they will auto follow any morph you use on her in Poser and Daz Studio without distorting or warping. If you need to make tiny adjustments to the location of the hooks just grab a hook bone and use the translation dials to move it into place. You likely won't ever need to use them on G2F if you have her head upright, if you have it tilted and need to use rotation on the hooks to follow gravity you will probably need a bit of tweaking on the translation. For minor gravity rotations it's better to adjust the ribbons instead of the hook, then they will need to no tweaking.
When using the earrings in Poser you will get the best results if you select the DangleRight and DangleLeft bones and turn of smoothing in the properties tab. They will still look fine if you don't but the gem beads won't look as sparkly. Also remember to morph your character before you load the earrings so it will pick up the morphs.
