You should take a look at OpenLayers.

You can make a webpage with OSM as the background, then add your own 
information as a transparent layer on top.  You can have many layers and turn 
them on and off.

Here is a very simple example:
http://wiki.openstreetmap.org/wiki/Openlayers_POI_layer_example

But there are many other examples on the web, and a lot of OpenLayers 
documentation.

Best wishes,
