I have some questions.
Area progression: when a new area gets unlocked as you level up, does that mean there’s no way to return to an older area? Or maybe there’s no real reason to return?
Player housing: I couldn’t find a yes or no on this, just speculation. Anyone know?
You can return to the area.

Some areas, phasing (or 'layering' as we call it) is not based on a choice, but on whether or not you've done a certain thing yet. In this case, separation from another player would be temporary. In other areas, it can be based off of a choice you've made. Those choices tend to come at the end of the activity for an area, reducing separation.
There are other mechanisms we use to reinforce choice that have nothing to do with layering. You may experience something completely different than someone else based on your individual choices, but the ways we show this don't separate you from others at all. The latter techniques are used far more frequently than layering. And finally, there are still other solutions we'll discuss later that enable you to better stay together with others even if you'd normally be in different layers.
No player housing. Zenimax said they might add it after launch, though.
PvP Info:
•When you join a PvP zone, you’ll be scaled up to approximately level 50. You’ll be able to hold your own, but someone who’s actually level 50 have more skills and abilities than you.
•Siege weapons can be purchased using Alliance points, and rams, ballistae, catapults, and trebuchets can be packed up and re-positioned.
•There will be a PvP rankings system. You’ll be able to earn Alliance Ranks which will grant you titles, as well as giving you access to purchase weapons and armor. There’s even a PvP skill line that you’ll be able to gain access to.
•Leveling through PvP will not be on the same pace as PvE leveling, because other players don’t just show up to die.
•Stealth/Sneaking is a factor in PvP, but there are ways to detect it. Damaging a sneaking player will reveal them , as will spells designed for that purpose. Additionally, sneaking using stamina, and therefore going into battle sneaking will put you at a disadvantage.
•NPC villages will be Alliance-neutral, but if you hold the nearby keep, guards will patrol the town, making it safer for you to do business there (But not 100% safe).
Other Game Info:
•Fast travel is in TESO. Once you visit a point called a Wayshrine, you can travel back there from anywhere on the map. If you’re at a Wayshrine, you can go to any other Wayshrine for free. If you’re out in the wild, it will cost you gold – you’ll also be limited in how often you can do this.
•Yes, you’ll be able to make and eat Sweet Rolls and Fishy Sticks.
•You will be able to loot items from houses, crates, barrels and the like. Plans are that respawn rates for loot will be fast enough that you won’t always find empty containers.
•You’ll be able to get most skill lines in the game, with a few exceptions. You can’t be a vampire and a werewolf at the same time, for example, and there are some class/racial exclusives.
