To be honest mate, personally I would take copies of everything, just in case. I'm pretty (but not 100%) sure that Gary won't need copies of his marriage and divorce papers as it didn't affect his surname, but I wouldn't stake my life on it. Ours was so long ago now, I can't remember much of what we had to provide. Get as much info together as you can. I don't think we brought over any bank statements, mortgage statements, etc, but to be on the safe side, I would make sure you bring copies of your divorce papers, copies of Gary's (just in case), and any paperwork from the last, say, 3-4 months (originals, if possible), then if you need them you can get them copied over here.
Sorry I can't be more help
