This post is almost three months old but seeing as how it hasn't been answered...
Prime 3 doesn't use .brres. Retro uses their own proprietary formats. The formats you're looking for are CMDL (model) and TXTR (texture). If you want rigs then you also need CHAR (character), CINF (skeleton), and CSKR (skin). There are no tools for the latter files but if you like you can use some crappy Maxscripts I made to extract CMDL/TXTR/MREA. (link)
