Never seen some of those maps (gloss map, specular map & so on), but you are able to set things like your diffuse and emissive, check out the 'Basic 3D' section of the help file. For the maps, you'd probably need to learn to write shaders.
However, for normal maps, there's a built in bump mapping command, it isn't as great as other normal mapping shaders, however, there are shaders in the
Ultimate Shader Pack, you ought to be able to get a normal map shader using Dark Shader and
Evolved's Website is a FANTASTIC resource for DBP specific shaders (complete with sample code).
