The only problem I have with Landscape is no one so far has a made a tutorial which goes from point A to Z with it, especially when it comes to creating the Blend-Masking via Displacement Maps and such, as opposed to the Terrain tool, which is limited to Vertex-Blending, but has all the bells and whistles covered in it, as…
Don't use Terrain use Landscape. They're two different things and landscape is much more feature rich. here's a polycount thread with some info and some tutorial stuff: http://www.polycount.com/forum/showthread.php?t=100011
A great tutorial about making terrain in UDK http://www.polycount.com/forum/showthread.php?t=88933 But if you're spamming the level with static meshes, then the terrain is going to be mostly hidden. So I would just sculpt a Landscape mesh in UDK.
