Marge's meeting in the city with her old classmate Mike. At first, the scene seems extraneous, but when Marge learns the truth behind Mike's dialogue the next day, during a phone call from her friend in Brainerd, she has the most subtle "Eureka!" Moment and is able to look at Jerry in a different way. Noted in Ebert's Great Movies retrospective of the movie.
The briefcase full of money that gets buried in the snow seems to have been Left Hanging. However, someone will most likely find it when all the snow melts come spring. The case and the money will most likely have suffered extensive water damage, but it should still be there for someone to discover by chance later.
Jerry is late to his first meeting with Carl and Gaear, can only offer weak apologies and remains vague about why he needs the money. Right from the start, the audience should twig how self-centered and bad at negotiating he is, reinforced in the later scene when he's handling the buyer angry that his car was delivered with an option he specified he didn't want (which Jerry probably ticked on the order form anyway just to increase his commission).
Jerry himself is probably going to be even worse: he's been arrested for his involvement in a kidnapping plot that spiraled into murder, he is probably looking at a decade or two in prison (unless he can get a plea deal), his wife's family blames him for Jean and Wade's deaths, his son will probably never forgive him, all of his business partners will abandon him, and when he gets out, his career prospects are less than bleak. He no doubt deserves it, but damn.
"And for what? For a little bit of money."
Also, GMAC isn't going to write off that missing $320,000. Since Jerry is going to prison and doesn't currently have access to any assets that we know of (who's to say his debt didn't see him mortgaging his house?), the company is most likely going to repossess most of the dealership's cars. How well they survive that blow is up to what kind of management structure Wade set up & their competence, but if they wind up going out of business, the economic repercussions will wind up hurting the salespeople, staff, and their families through no fault of their own.
Grimsrud murdered Jean because "she started shrieking". Was that purely because of her terror, or because he assaulted or even raped her?
