I'm not sure if you alreday got some answers... as they didn't go over the  
list, I just tell you what are our experience.

We have 'till no characterised 7 complete (extracellular) gene loci in  
zebrafish, mouse and human in great detail. What I can say from that is:

+ The intron size in zebrafish is equally long as in human or mouse  
(although we didn't look exactly in that).
+ The intron length is not conservered (but is also no very well conserved  
between mouse and human).
+ The "exon phase" and "intron type" ist very well conservered.
+ The exon number and coding information (which domain od the protein etc)  
is mostly conservered.

Hope it helps... You have to judge for yourself if 7 genes is enough to  
draw conclusion for the whole genome ;-)
