Ok guys.... i am  new to Poser, so i am still trying to get along with it

Now, i have this question: Why when i buy a car, a city or some props they're  like "tied' or grouped but still i can mange to change or move the direction if i select a piece?... i mean, can i do this will all my characters ?/???

I have this character or props (a gun maybe) when i click on it, it is pieces... can I group it together?or maybe a character i crated and dress full with it's morphs.. is there a way to make it a group? and still keeps all his morphs?

When i save a character on my library and then i loaded again... it looses ALL the morphs!.. or must of them... what am i doing wrong?

i have these cool guns but every time i try to move them i can only manage to select a piece of it...
i know it's a dumb question for i don't know what to do in any of those cases!!

Help me
