Yes RoR is one of the key technologies used for the OSM website, but
then we also use PHP(mediawiki), Javascript(OpenLayers), Flash(Potlatch)
and probably several more too.

You can not get _all_ the data (some user details remain private). You
can download all of the map data which comes as a 5GB compressed file.

For normal purposes I recommend you work with a one of the smaller data
extracts listed on this page (unless you have lots of computing
resources and a need to process the entire data set).
