QGIS (1.7) > Plugins > Save as SVG > Save as SVG > Choose the path > Save > ok. An clean .svg file and .png background are produced, thus providing both the raster and vector layers. Inkscape works! It is now up to you and Inkscape to change the style of each svg group / item, and to add further content (icons, labels, legend, etc.)
The layer s QGIS work like layers of Inkscape; Highly recommended reading articles Tagged Image File Format and Shapefile; Georeferenced file (either vector or raster) ≠ non-georeferenced file (either vector or raster); Graphics software (Inkscape) ≠ mapping software (QGIS can "read" the georeferencing of a file);
1. Add Vector Layer, 2. Add Raster Layer, 3. Remove Layer(s) Loading a GIS file adds the data into your project as a layer. For our purposes, we care about vector layers and raster layers. There are three ways you can add layers into your project: using the menu, using the keyboard shortcuts, or using the toolbar icons.
QGIS supports raster, vector, mesh, and point cloud layers. [4] Vector data is stored as either point, line, or polygon features. Multiple formats of raster images are supported, and the software can georeference images. QGIS supports shapefiles, personal geodatabases, dxf, MapInfo, PostGIS, and other industry-standard formats.

Raster data is computationally less expensive to render than vector graphics Combining values and writing custom formulas for combining values from different layers are much easier using raster data. There are transparency and aliasing problems when overlaying multiple stacked pieces of raster images.
QGIS display your data using the projection you tell it to use. By default, the lat/long projection (= Equirectangular projection , example aside) is used, code: WGS84 lat/lon (EPSG:4326) . This projection is the most convenient for georeferencing, but imply strong distortions at polar latitudes.
Merge layers is based on their nature : vector or raster. This later ease later application of color style, layer management, and files/project sharing. For raster such as topographic data (SRTM, ETOPO, etc.), shaded relief, natural earth skin, ... use : QGis (1.6) > Raster > Merge > (merge window pop up)
