Yes, as of 8/17/11, Ichigo officially gets his powers back. Since chapter 429 when he first meets the Fullbringers, he has perfected Fullbring which, at first, resembles his Shinigami powers. In chapter 459, Ginjo turns out to be evil and steals Ichigo's Fullbring abilities and whatever was left of his Shinigami powers (even though the Final Gutsuga Tenshou used all of it). Right as Ichigo gives into despair, Rukia shows up and stabs Ichigo with a Zanpakutou. (just like in the beginning of the manga). The sword was made by Urahara and had the Reiatsu of several captains and lieutenants including Toshiro, Renji, and Kenpachi. All of their combined Reiatsus give Ichigo the ability to re-create his own Reiatsu source. After a cloud of dust clears, Ichigo's newest form includes his old Shinigami uniform (with new elastic bands around his neck and wrists) and a ridiculously larger Zangetsu. In terms of power, Ichigo still retains his speed and strength. But in chapter 460 (when we first see him fight with his powers back) he seemingly uses Getsuga Tenshou at the same strength when he lost his powers, but it was actually him just releasing pressure from his sword. The chapter ends with Ichigo saying, "Getsuga...Tenshou." Thus inferring he is going to use a real Getsuga Tenshou. Hope this answers your question!
No. ichigo does die yet in the manga they are currently at the part where chad and his buddies try to get his powers back. So i am pretty sure that he will not die yet
Yes his powers are stong and very distructive at that
Due to the fact that hollow ichigo's powers haven't been fully demonstrated or explained, we do not know
Yes, when he lost his shinigami (soul reaper) powers for the first time he lost it. he doesn't get it back when he gains his powers again in the latest arc.
Due to the fact that hollow ichigo's powers haven't been fully demonstrated or explained, we do not know
By doing an hard training with Uhara
He never completely dies, he's a part of Ichigo himself. Ichigo beats him and steals his powers though, and basically neutralized him. He's still deep within Ichigo though, waiting for a moment of weakness to make his presence known.
She transferred all of her powers by accident to Ichigo when a hollow attacked his family. Therefore, she basically lost her powers. In addition, Urahara placed the Hogyoku inside her gigai preventing her to regain her powers. Rukia then gained her powers back after Aizen left the Soul Society.
Sadly...yes. Soon after he hits Aizen with the final Getsuga Tenshou, his shingami powers fade away. I've heard rumors that he might get them back, but who knows...It all depends on Tite Kubo's decision. I hope he does!!;)
yes. when she gave her powers to ichigo, the reason she couldant regain her powers is because she was in that gigai. when she went to live in the soul society, the plentiful amounts of raishi in the air restored her powers
After Mugetsu, Ichigo loses almost all of his Reiatsu right after the technique. He will then gradually and slowly lose the rest of his Shinigami Reiatsu in a month or so. It is possible to regain those powers afterwards, by developping your Fullbring (What Ichigo actually did :D )
A visored is a soul reaper who obtaind hollow powers so yes
