Add Permalink code to web.config

Hi, I’m not a programmer but managed to get the following domain redirection to work with “ugly” permalinks (www.lacjustone.com). I would like to switch to pretty permalinks but I need to add the standard code needed back into this web.config without breaking my redirection. Help would be greatly appreciated. Thanks.
