I’d second qgis as a way to bring data into your shapefile.

Also cartodb.com understands shapefiles (or geojson) and gives you a decent way to create an online map from it.

For Germany, check out:

The most common issue with German municipal ("Kreis") level data is the fact that the regional delimitations (and hence their AGS ids) change surprisingly often, the last major reform was in 2009 and affected most of Mecklenburg-Vorpommern and Aachen. If the municipal AGS in your data and your map files don't match up, the first thing to do is to make sure that both refer to the same year. This makes comparisons across different years (or even decades) an incredibly tough thing to pull off.

In terms of tools: QGIS, and the tools mentioned here around topojson and geojson ;)

Cheers,

You can also try with topojson and d3 -  http://bl.ocks.org/mbostock/5925375
or leaftlet and geojsoncss -  https://github.com/albburtsev/Leaflet.geojsonCSS
