Look at it this way: when representing a distance, I'd tell you X and Y have a distance of 3000 meters between them. I can also tell you that they are 3 km apart. Although 3 is negligible compared to 3000, here it's all about the scale and unit used. Another example, when talking about celestial bodies, 3000 km is nothing for them (when compared to the distance between the earth and the sun), but it's a big deal to us tiny humans. Here, I am using a scale to fit the average human of their world, as life's gotten easier for them, therefore their constitution has dropped significantly over the years. The average CON for TWD is 4.
He might want to consider grinding sword and archery skills. The zombies are very easy and numerous so it'd probably be easier to grind skills with them first before moving on to Westeros. He can also stock up on getting a couple high-grade compound bows and arrows. Stab-proof clothes maybe if he can find them. Just good clothes in general really for all weathers. One of those water-filtering canteens and antibiotics. He could also raid a bank or jewelry store for gold. I don't know what his limit is but if he can store an entire library of books then he should be able to carry off a lot of gold. Though perhaps most important of all he should remember to stock up on toilet paper, shampoos, soaps and toothpaste. No one seems to remember how filthy you can get in medieval periods.
