A:AnswerActually if your using your external hard drive from your old console you can just plug it into your new one an you can select it that your using it for both consoles.
A:AnswerYes. I reccomend a Game Pass Subscription. The ultimate version is 15 a month and you can download or cloud play hundreds of games at no extra cost. When you consider one game can cost upwards of 70 bucks, it would take more than 4 months to spend that with the sub and you can play games from several generations back right up to some games that are just now releasing.
A:AnswerAll gaming consoles regardless of brand generally come with one controller. So yes.
If you want a second controller it needs to either be bought separately or as a bundle
