The immediately good news: the 2.0.1 version of Hebrew OpenOffice.org is out - go and download it! It features a whole bunch of bugfixes, primarily fixes to the way tables in Word files are imported. I don't use Word much - particularly not for Hebrew files - so I can't righly comment on it, however I've been told by friends and peers that this bug was one of the biggest issues they had with the 2.0 Writer.

Also, a tip: it's not obvious nor exactly trivial, however it IS possible to do regression analysis and include trend lines in Calc sheets and charts; check this tutorial out (via xslf on the OOo.il forum).
