In addition we have the fight against itachi and sasuke which we take quite enough.Naruto should meet up sometime with sasuke too.We haven't seen anything about the new shino,kiba,neji(not much) and the other chunnin.Kabuto is a mystery too what will happen to him?The questions concerning akatsuki are toooo many...Anyways we still have a long way for the end of naruto series
Well, like I said, I'm talking 2 to 4 or 5 years, that may be long for you, for me that doesn't seem to long, and it's surely not long in terms of the manga industry. All the things you mentioned, every one of the backgrounds, those could all be fully explained and done with within a few months. Take time to discuss those in the manga, have them get things worked out, maybe a few conflicts here and there, but mainly discussing their backgrounds, as you said, and their mysterious motives, all of that could easily be done in half a year, maybe more.
Think of how fast it took to discuss Kakashi's story, a few weeks? Yes, there are still a few things missing, and there is surely more to learn, but we learned so, so much about Kakashi within a few weeks, the Kakashi Gaiden arc provided us with that. A few weeks, that's all. Take those characters, who are much, much less of an impact in the story than Kakashi, you'll have yourself a very quick flashback.
