I did this on our K12LTSP 5EL install:

- Install gconf-editor (yum install gconf-editor)
- Start gconf-editor as root
- Navigate to /desktop/gnome/url-handlers/mailto
- Replace 'evolution --component=mail %s' with 'thunderbird -compose %s'
- Right-click the key and select 'Select as Default' (you can also  
choose Mandatory if you do not want to allow your users to change this)

I think it's strange that they'd choose randomly. We have startx on  
01 and shell on 02 and all clients boot to X by default.

You'd have to modify the GDM theme. I didn't change the theme, but  
just set remote logins to use the same GDM theme as local logins,  
which gets you the default CentOS/Fedora login screen. I think the  
CentOS 5 theme is pretty slick.
