The number 1 way to fix many of them: install the game to your hard drive! This will get rid of some of the stuttering and other small problems, as well as decreasing load times and saving some wear & tear on your 360's disc drive.
Expect it to take from 5.9-6.7gb.
As mentioned in OXM, you also don't want to mash A or start to get through the intro logos when you first boot the game up. Let it slide through them!
If you have any interesting or fun stories from the game, post 'em here. I am going to purchase this very soon, mediocre reviews be damned, and I have been looking forward to it ever since I saw some Atalanta concept art way back when.
