I think most programs would use the kernel drivers anyways. So you'll have to enable it. If your in luck it could be available as a module and an insmod would be enough. Once you got that working you should be able to just mount the cd and access it like you would for any other filesystem.
You can find the UDF toolset here:
http://sourceforge.net/projects/linux-udf
But you will still have to have udf filesystem support in the kernel to use those.
I don't know what you mean by UDF rading. But UDF has been chosen to be used as the file system for 2nd generation high capacity cd's like DVD's. So I assume it's an improvement to the ISO9660.
