Unity supports .dae files. Simply go to Assets => Import New Asset, browse to your .dae file. It should take a moment to update your assets, then just file it into the appropriate folder in your Project window (contains all the folders for your project). Filing is not vital, but just helps keep organized.
Your mesh will not have the material on it. If you need to, import your texture into Unity as well, file appropriately, and apply it onto the 3d mesh (you can do it directly onto the mesh on the screen, or click on the mesh (.dae file), and in "Mesh Renderer" apply the texture under where it says "materials", in the Element 0 slot. Changing the variable of the size will determine how many materials are applied to that mesh.
As for your terrain question, make sure your terrain is selected under the Hierarchy menu. Then click the button with the mountain that has an arrow pointing up. This is the raise/lower brush. Holding shift while you use the brush will lower the terrain to make trenches or holes in the ground.
Ins$$anonymous$$d of applying the materials manually after the import, try importing the images first. As suggested by Jeff $$anonymous$$esselman : http://answers.unity3d.com/questions/167548/collada-import-with-textures.html
