Do a few weeks without any assistance while you adjust to the demands of the program. Once you've adapted, add in an exercise or two to see how your recovery is. Volume day is the hardest day of the week, so don't get too carried away with accessories on it.
I'd put most of your accessories on recovery day. Dips and chins won't burn you out, so stick them here if you want them (maybe add GHR or back extensions if you have one available).
I preferred deadlifts on volume day. It seems like a lot, but between setting up for bench, doing the warmup and worksets your legs should get around 30 min rest before you pull for one final set and you're done.
Plus, volume day already takes long enough just trying to get through the squat and bench 5x5... the last thing I'd want to do at the end of it was 5 sets of rows. I'd put them on intensity day.
