For the first issue, MS has heard, and is addressing that on the 360, so I would assume that they would keep it in for the next version.
Basically, if you're an XBox gold member (which from your post you are), with the most recent dashboard release, they allow you to save your profile, and game saves to the "cloud". So now, when you finish playing something downstairs, you can go upstairs, and continue playing from there, without needing to migrate your existing gamertag. (Although I've not used it, I would expect that you can only use your gamer tag on 1 Xbox at a time.)
