I may misunderstand what you are asking, but there could be an even easier way to get ArcGIS Online raster basemaps into ArcMap. The Add Data tool in ArcMap will allow you to import a wide variety of data from ArcGIS Online, including basemaps. It took me a while to learn about this when I first started, so I won't assume that you are already aware.

Daniel, I am glad you might be able to make some use of the USGS site that I mentioned. Actually the part that I thought might be the most immediately useful for you was the hydrography vector data. I am including an image of a quick map I put together using only a single 3 meter DEM raster and the USGS hydrography vector data. I created hillshade and contours using the Surface toolbox in the Spatial Analyst toolset (ArcMap 10.1). I applied standard elevation color ramp symbology to the DEM layer, made it partially transparent, and placed it over the hillshade layer. Then I placed the vector layers (hillshade and hydrography) on top of that. Its pretty rough, but may give an idea of some of the potential of DEM data for your purposes. It should allow for a lot more customization than using a pre-made topo basemap.

In the World Mineral Deposits map that I have used, the main data layer is nested within a group layer (or the ArcGIS Online equivalent). Clicking the arrow to the left of the group layer, in the table of contents, will reveal the sub-layer, and then the table and other capabilities will be accessible when hovering over the sub-layer. Hope it helps!
