No doubt there are other measures besides h, but you can't use h in the ways you have suggested.  I wouldn't have mentioned it but I've seen you say this a couple of times now.  h is always biased when comparing earlier versus later years.  It's like comparing the balances in bank accounts that have compounding interest.  Earlier deposits always have an advantage over later ones.  A less biased method would be to compare monthly deposits, not compounded balances.

You can limit yourself to papers written in a given timeframe and
calculate the h factor. For example 2002-2006 versus 1998-2002.
Compare the amount of papers before 2002 with the amount of (yearly)
papers afterwards.

Surely there are better or more relevant statistics to understand the
value of G's work than just a number like h=20 or normalize h=13 or
350% exceeded?

See http://en.wikipedia.org/wiki/Hirsch_number for some top h-index
candidates. There is no reason to limit the calculation of h-index to

Also, publications per year

2007 1
2006 3 (excludes text book)
2005 2
2004 2
2003 10
2002 7
2001 4
2000 6

Web of Knowledge has many of the tools to do all these 'experiments'
