No it does not end at episode 366. It will continue after the manga has gone a little further. Otherwise they might use fillers,but these said filler(being sub stories within the anime which have little to do with the main story) are considered bad among the views due to the fact that the manga goes far beyond the anime. So it will definitely continue.
Episode 366 of Bleach corresponds with chapters 476, 477, 478 and 479.Note that those manga chapters end differently to the anime episode as the anime ended there but the manga is still on-going.
As of 3-27-12 there are 366 episode which is the end of the 16th season and as of right now no further episodes will be back on because Bleach the anime has been cancelled in Japan...
Bleach will continue in the next year,or for the long waiting.

It will most likely not, but if it does, they are still making the manga.
Yes. In fact, it's the last arc in the manga.
No, They're going to Dub the show tell the end of the series.

bleach isnt really in seasons and its more along the lines of arcs... with the arrancar arc being the longest if you consider its the main story and starts with episode 1 and continues for around 250-270 total episodes without the fillers / side arcs
