A female Doctor has been something speculated about for eons, and of course they did it in the Children for Need sketch from the 90s (aka The One Where The Doctor And The Master End Up Deciding To Get Married), and who knows, they might do it one day - but not with Rose. Aside from the necessary human/Time Lord transformation (which could be gotten around via various Whoverse means, even leaving the Chameleon arch aside - the Master when running out of regenerations back in ye olde days went into bodynapping, for example), there is my very big doubt Billie Piper would commit as a lead or anything but a special, a season at the utmost, the way her career has taken off and they're not doing an Eccleston again. (DT's career has also taken off, but he's a genuine fan of the show, so able to commit.)
The Greg Doran (= director of the RSC Hamlet) interview I linked a couple of days ago has Doran mentioning, re: casting Tennant, "there was a long time where we had to keep it under our hats whilst the BBC sorted out his temporary vacation of the TARDIS", so, "temporary".
Martha and the clone: that has been answered by others, I see (i.e. the clone originally took Martha's clothes and the ring, Martha took it back).
Re: big companionalooza: if you've watched The Sarah Jane Adventures, my suspicion is that something from Whatever Happened To Sarah Jane? will come into play there. In said episode, the villain temporarily changed the universe and took first Sarah Jane, then others out of it (they either died as children or never existed), and he specifically was interested in the Doctor from Sarah's memories and said he wanted to go after him. I suspect that's something that will happen (and also why Elisabeth Sladen is scheduled as one of the many guest stars at this season's end), and the Doctor-lite episode this season is one where we get to see the universe where he didn't exist or died a long time ago, and then the companions will work together to put the timeline back to Doctor-existence.
