You can easily produce your own editor. This is the easiest thing. Walk trough your world and add a fileselector that will let you choose a mesh to load and position.
Alternatively I have released pledit, a placement editor for plasma, open source: www.melog.ch/dl/pletid05.zip
Loading the parts of a map as individual meshes mill make it easier to check for collision in the game. If you load everything as a single mesh, you need to identify the surfaces to find out more about Collisions. And evn then it may be impossible when you have two Houses on the terrain which use the same brush, the may be part of the same surface.
Using an editor that will let you position meshes will surely need a loading source that will load your creation exactly the same way as you created it. So in the end it mihgt be as easy as "success=loadlevel("mymap.xyz")"
