Textures on Terran

[Ultimatony]

How do I add a texture to the ground after setting down the invisible ground tile like in: THIS

Are there some in game i can get to easy?
What pixel size should it be to fit in a 1x1 2x2 4x4 square (size editor calls some ground covering doodads)

Found some in Ultimate Terrain pack but none look good like wood floor or brick.

Do the stairs work for units? or do you have to set the terrain under them to the right angle?
