I was wondering, is there information available to learn putting those
beats into notation? What 'symbol' belongs to the bass, hi-hat etc.
Is there information on the internet about it? Or does someone knows a
other method (good book) for it?

And how easy is it to match the notes with a drumkit in for example
hydrogen? I think it should possible to play the drum score in
Rosegarden with Hydrogen as a synth..

Sure there is!

Here's an introduction to drum notation:

And the Lilypond documentation has a nice overview of which "pitch" maps to what drum in different notation styles:

When it comes to drums and MIDI you have a choice of drum maps (which note maps to what drum) either standard GM drum map, the nifty MC505 map or some custom map (because every drum kit is different and MIDI should be regarded as "recorded performances" and not as "notation" -- although most maps is usually compatible when it comes to basic kick, snare and hihat).
