How do you group objects together so that when you move the model, an object and or prop moves with it? For example hair. After adding hair, how do I link it to the model or head so that when I move them, the hair moves with them? If there is a way, does it also work for basic props? Thank you,

With the object selected, for example hair, select from the menu 'Figure/Set figure parent..'.
Scroll to 'Head' of the figure and click it. Click ok.
And the hair should be parented to the head.

re: "If there is a way, does it also work for basic props?"

Yes.

You can "glue" them together.

Export all the objects you want to have as a single object to a Wavefront OBJect... file.

Then, Import that file back into Poser and it will be a single object.

If you have group data for the objects, make sure to check "Include Group ..." when you Export ...
... or you will lose that information.

If you want to keep the same size (scale) ...
... make sure to UNcheck the "Percent of Figure size" when you Import the file back into Poser.

Given a choice, I think parenting is the easier way to go.

When I attempted to parent the hair to the head, the hair repositioned itself somewhere else on the stage. It changed position and went down by the feet. Strange....

With hair, most hair is either a smart prop, which should load parented, and in more or less the right place on the head of the currently selected figure. Or confoming figure hair, in which case it should be conformed to the character (Figure > Conform To, then select the character from the list). With items such as weapons, books, umbrellas, these should usually be parented to the appropriate hand of the character. As to grouping a number of props or figures together, the most flexible way is probably to parent the items to my 'MinFig' available in the Free Stuff. This not only allows you to scale, rotate, and translate, all items parented to it, but you can also save the whole group (props , figures, cameras, lights) by resaving MinFig to a pallet. Locking MinFig will also lock any props, lights, or cameras parented to it (but not figures). Hiding MinFig will hide any props parented to it. For just translating, rotating, and scalig a group, you can parent the items to a Poser SQUARE prop then hide the SQUARE.
