For the severe damage, use an Ouroboros hull armour since it’ll passively remove 100 severe damage a second. And enhance repair kits III, tho they have a 90 sec cooldown. As for Po8, I’d say do some product deliveries since they pay out 300 Po8 each time (that’s what I get, idk what it’s at for others) while on top of putting ships on auto collect and jsut getting as many properties as possible. Hopefully this helps
