For the barking problem try the pennies in a can, it seems to work wonders and will quiet them right away. Also, teach her to bark on command. Once she barks on command reward her. Then have her bark on command and then quiet her right away and reward her big time for being quiet. I know this sounds like you are teaching her a bad habit, but actually you are teaching her, once she learns, that she gets lots of rewards and praise for being quiet when told and no treats, no attention or praise when she barks.
As for the pad training, be patient and consistent. Start back at square one if you need to. I always suggest crate training, it is so easy and it it the quickest and most successful with house training. Always take her to the pad and don't let her get off of it until she goes.
Hang in there, it takes time and sometimes it seems so hard and impossible, but it is not, just be consistent and patient and it will pay off in the end.
If you have any questions, just ask me and I will be happy to help you any way I can.
