Its been a couple of days and I wanted to give another, likely final, update.
First and foremost, the EASY schedule for us with the additional feeds is working!
That was my primary question and having gone at it a few days, I can safely say we are getting the hang of it (baby and I)!
Secondly, the weight issues...baby is definitely gaining weight!
Yeah! I have charted a small but steady gain over a few days. Nothing crazy, but a half ounce a day it seems, which was the rate she was growing at before when she held firm on the 10% range. So I think we're doing somethinig that is working for her and I'll just have to follow her lead on when to wean off the night feedings. She's still waking up throughout the night, but sometimes she'll extend the hour to 2-3-and (gulp!) 4 hour stretches. Those are only once a night, and certainly not every night yet. But it's a sign that we will get there as they become more and more frequent and then longer and longer stretches again.
Lastly, the sleep issues. Now that the first two and most important two things are working themselves out, I think I can start looking at working on the nap training. I just look at her and although I'm keeping her on her reflux meds, I'm just thinking more and more she is growing out of the problems she was having as we're having no spitting up or screaming episodes anymore. What a relief because that would save us from more insurance issues and Dr. check-ups!
I think for the sleep issues, so far it's going pretty well. We've done 60-90 min naps for the most part. I think that's great. We did have a 3rd day relapse which was not good because DH still firmly believes that we should never wean her off bouncing her to sleep so of course when PUPD was taking longer to work he swooped in to do the bouncing. But it didn't work either then he just handed an awake baby to me
and we missed that nap completely. That was not fun,
but we talked about it and finally he agreed to support me in the BW training since the benefits are for the long run. I did have a hard time again this morning. But honestly, while she was crying I read Tracy's Sleep Interview and went right to the 6-month Touchy baby and tried the technique she said. Within 3 minutes my baby was asleep.
This stuff works! No doubt about it! So if I have any further issues I'll check the materials I have first, then maybe just go to the nap board for a new post, if needed. Or the general sleep issues board if we're having trouble at night.
Thank you so much again! How can I "show appreciation" like your side bar requests? 
I'd like to do it for all the women that posted and helped me along the way. My trials are still going, and I am still very fatigued but I know I'm doing something that is working and she is gaining, so I think that's all I can ask for right now.
