** In Poser you can only pose, not arange pieces accurately. Or build anything ** This is not true. It takes patience and 'micro management', but you can really achieve very detailed 'arrangements' with those and some practice. As for building, that's closer to true, since poser is not a 3d modelling tool. But combining and reshaping even just the primitive props, and using properly textures, transparencies and displacement maps, you can do plenty of seeming impossible things... like buildings, fences, terrain, water... and many more 'scenery' stuff. And as already many pointed out, manuals and tutorials really are a must! Then move to browsing the forums and communities for looking at what other users made and how they did. This is a really good place to start, another one with good tuts and freebies is runtimedna.com. Welcome on board, and... most important: have fun!
