Hmmm... mud can at least flow a bit, but I don't really see what you want to get to.
If you bought stuff at Daz, first thing to know is: which format? Daz installers can install Poser and D/S stuff and some items install for Vue as well. If you run the installer for Vue, items will be placed in the folder you see using the installer, typically my documents/e-on software/vue 6 xxx/ objects/....
They follow the cornucopia3d scheme for installing stuff, like objects/outdoors/fencing and such.
If there are some ecosystems already made by the item's creator, you will find them in materials/ ecosystems/...
If the stuff you bought is Poser or D/S, you first need to load the items in those apps, and export.
In Vue, import the item and save it as a .vob (vue object format).
