dont VW use TRW brake calipers etc as standard (in the mk5 platform anyway) ? so i wouldnt have any worries about going for those items. makes sense to replace the lines while you're there though. at least then you'll have a complete new set up. for the sake of a tenner each for the hoses.
i like painted discs too! i'd prefer silver paint though as it would look better through my wheels (personal pref)
