Re: itachi's gift
Isn't the requirement to read the tablet is to have at least a Sharingan eye or Rinnegan? Which in this case its impossible, cause Itachi never give Naruto his Sharingan. Besides, in manga, doesn't Itachi said something like this: "I have given you some of my power, I pray that you won't have to use it". This fact concludes that despite its only "some" of his power, the wish to not use it unless its absolutely necessary gives hint on its strength. Honestly, I have no idea what that gift is, but i came up with some suggestions on what it might be (Although its possible that its neither one of the list). This is what i think it is:

Since the wind part will feed the fire part with enormous attack power, It could be something that's so dangerous Itachi prefer him not to use it.
2. Some sort of jutsu that allow Naruto to tap into Kyuubi's power/chakra in a more advance way, allowing him to draw out more of Kyuubi's power. This too is very dangerous. Since sharingan is not necessarily needed to control a bijuu (First Hokage) and the fact Uchiha Madara controlled Kyuubi during the attack on Konoha 16 years ago, It's possible that Uchiha Itachi has come up with a way to do the same thing (Uchiha Clan).
3. Jutsu that the Sage of the Six Path used to contain Juubi in his body, as a last resort incase its needed...this too can explain his concern about Naruto's using it.
Basically..This list is pure imagination. It can be one of those, which i doubt it somehow. It can be neither also, which is very likely. Either way, thats my opinion on Itachi's gift to Naruto. Peace ^_^
