As you know, nginx by default doesn't support displaying file upload progress. But we have an nginx module: http://wiki.nginx.org/NginxHttpUploadProgressModule

Question is, how can i install it? How to recompile nginx correctly so i won't mess up my webserver?

You can replace default nginx package with with no consequences, just be aware of the configuration files in the /etc/nginx/conf.d/ directory
