1-Margery dangled her brother as a suitor to sansa, but, A- He doesnt like girls, and B- he's a member of the Kings guard, which to my understanding means he gave up the right to marry or be in line for titles. (now most of the last part i got from teh tywin/trion confab, so maybe thats just the rule of the Lannisters)
Loras Tyrell isn't currently a member of the Kingsguard in the TV series, though in the books he is (he's granted a place after the Battle of the Blackwater, especially since there are... ahem... some openings). For this reason, in the books Margaery and the Lady Olenna offer to have Sansa betrothed to
Willas Tyrell, eldest son of Mace Tyrell and heir to Highgarden.
I'm guessing they'll just omit the Willas angle from the series entirely and focus instead on Loras, who viewers are already familiar with.

They've bungled this a bit, in my opinion. It seems the writers have wanted what's happening to Theon to be a tease, and I can see the value in that, but they've really drawn it out. The basic idea is... he's in for some rough treatment. The guy who seemed to be helping him at first is, unquestionably, a very very bad person. Those who have read the books already know this.

The Brotherhood Without Banners isn't totally neutral. They're primarily opposed to Lannister forces, who have burned villages and brutalized the smallfolk since the war began. Remember, Beric Dondarrion was originally sent by Eddard Stark (then Hand of the King) to hunt down Gregor Clegane (a Lannister dog) and stop his raiding in the Riverlands.
That said, in the books the Brotherhood does eventually start hanging Stark bannermen, but only those who have taken to burning and pillaging too. You can chalk these actions up to the wandering forces of Roose Bolton and others, not soldiers of Winterfell.
Also, in the book, the Brotherhood holds Arya because they want to ransom her to her mother's family, the Tullys, in Riverrun. (They need the coin, being an outlaw group and all.) This could be the reason they're holding her in the TV series as well, but I can see Austruck's reasoning too: that she's a lord's daughter (and that lord is Ned Stark, who sent them on their mission in the first place), so she'd be worth scooping off the road out of honor and decency.
