If you have the correct mod_rewrite.so file available you don't need to compile anything.
If you need to make changes to the server configuration, you will need to restart the server process.
If you are making the rewrite changes in an htaccess file, you don't need to restart anything (as long as htaccess is enabled).
I am not so familiar with 2.0 - I don't have any systems left where I can test things (we retired our last SunOS 5 system last summer) - so I can't give you more specifics specifically tested on 2.0.
