um i'm pretty sure that u can only use up to a 2gb but not sure if they fixed it yet. i think u can use a slim but it has to be on a cfw. hope it helps

1. 256- 2gb only
2.no, you can use a pandora battery (if hardmodding it)
3.no, if you hard mod the battery, then all you need to do is add the files to you mem stick
