Ok, final product. I have no idea why I didnt end up doing the wheel wells, but no big deal, will be able to reach them even with floor installed so can do them later if needed, was just me being stupid in the moment I guess...
And the front seat area was nearly perfect. couple places that where scratched and 3 spots of tiny surface rust so I decided to tackle it down the road since I am not installing anything permeant in the front and have to take the seats off again later when I do swivel seats. ( the paint was simple, the cleaning and cleaning and cleaning needed to get the caked on grime off the van was killing me tho LOL.)
Anyways here is the image of the back after I painted. definitely learned a few things like I never want to use a non aerosol paint delivery system again if I have a choice!
The place on the right of picture where the seam sealer gets sloppy looking is where I replaced it. The 3m seam sealer I used worked fine and seems to have properly set. And I was able to use a normal caulk gun to apply it so that worked well also!

Anyways wanted to thank you all again for all the assistance! I am slow about stuff and it took me longer then planed but its done.
