I have recipes that call for either powder or soda, but not both, so I think that part of the recipe is fine. Just make sure your baking powder is a double acting (it'll cause a reaction for rise when you mix the ingredients and again when the cake is baked).
It also doesn't say when to add the pulp
I'd fold it in at the end. That much pulp is going to be a lot of berries!
And I'm sure you're right--pushing the berries through a mill, strainer, etc., will get out the seeds but keep the juice and pulp.
As far as baking instructions go, I'd try 350, the standard temp, but check it a lot! I'd think it'll be a really moist cake so you may always get some sticky crumbs on a cake tester/toothpick, but just make sure it's not to wet in the middle. If that's the case you may have to up the temp. I have a blueberry cake recipe that is baked in an 8x8" pan at 400 but only for 25-30 minutes. Sorry I'm not much help on that part--if it were me, it'd just end up being a lot of trial and error.
Good luck and let us know how it turns out!
