I'm actually confused about the Sansa situation. What exactly do the Lannisters gain by marrying Sansa to Joffrey at this point? If they were assured of victory, it might make sense to proceed with the marriage, as a means of healing over old wounds and giving the defeated Northerners a stake in the future regime. But right now, with Robb winning, the Lannisters' primary concern should be to win over new allies, and marrying Joffrey to someone else would be a great way to win new allies. So why is Sansa still the fiance, instead of just a hostage?
I will try and not spoil things for you, by only using things known from the show explaining the matter of Sansa's still-betrothal

So what we now from the show is that Robb can fight the Lannisters forever, but he won't win unless he takes kings landing and other important Lannister strongholds and that he can not do that without a navy (that's why he sends theon to treat with his father balon greyjoy).
The other thing we know is that Robb hasn't won a victory against a lannister army led by tywin lannister himself and tywin is an experienced und brilliant army commander, so he is sure that he will defeat robb stark in the end, also the lannisters have like unlimited ressources, if they run out of men, they could just hire thousands of mercenarys to keep on fighting for them.
So if Tywin manages to defeat Robb Stark and execute him, Winterfell and the north would pass on to Bran and then to Rickon, both beeing kids. Tywin Lannister did kill the Targaryen children he could get his hands on, so killing another two boys wouldn't be that hard for him, which would make Sansa heir to Winterfell, so if this scenario should happen he could marry Sansa to Joffrey and BÄM the north is rulled by a lannister by legal ways.
This possibility, together with the knowledge that a marriage to no other great house would bring in as many benefits to the lannisters as the starks right now (the tyrells are already renlys bannermen, the martells hate the lannisters, the vale hasn't got a female heir, hoster tully nor edmure tully have a daughter which they could marry to joffrey nor would they if they had, the iron islands are insignificent to the lannisters and are looking to have some disputed succession after balon greyjoy dies).
