With DB, you have to make your own models, with a program like milkshape, 20 bucks (US) www.milkshape3d.com its great, made for half life models, thats how good it is. Simple uses it, and so does act. and they are two of the best modellers here. Not to mention our modeller, who is also great
As for a world maker, it depends on if you want an outdoor style game, or indoors. For indoors, Id try the Cartography Shop, for outdoors, id go with MatEDIT (www.matedit.com)
Catch me on any of the instant messengers (below) for more info.
Hope this helps you,
