yes but currently the plugin is not part of the public release.   
However RC5 will see the new grid coverage implementation and as of  
then many of the "unstable" plugins will be part of uDig and the  
current plugins will be much faster and stable.

Also possible.  You can use java.awt.BufferedImage to create an  
image.  Then ImageIO.write( ) or something to write to a jpg.

There is an add Layer Interceptor extension point which allows custom  
code to be ran when a layer is added to a map.  You can use that to  
set the style on your layer.

Shouldn't be very hard to do this.  I am very often on the  
freenode.org#udig IRC channel.  Feel free to contact me and others on  
that channel to chat with us.
