well.
You could have numbered your ideas, so I will respond to them section by section.
1. Torments are meant to be frustrating, hence you can (currently) resurrect one time, then usually not until the new day when you die. it is meant that way.
2. I won't sell stat points, because that would make the game way too unbalanced. Check the things you get for DP, there is no extra weapon or whatnot inside, only Hollow Ichigo for a limited number of days.
3. Nope, it's enough =)
4. See 2) for the reason why.
