Yes but, you have to hack the x-box believe me I've looked online for hours
You can purchase Microsoft points from any game store or online.
The Xbox Arcade is an Xbox 360 and it comes without a hard drive. What you are calling an Xbox 360 I'm assuming comes with a hard drive and if you are thinking of buying an Xbox I recommend not buying the arcade as you cannot save games without a hard drive.
No,you can not but you can download them.
No, by buying a gold membership card you just get Xbox LIVE access. No Microsoft points. But why would you PAY for your Xbox Live? You can get a FREE Xbox Live Gold Membership for free with the help of my site. It even has a video tutorial to help. (LINK at bottom)

No, XBox Live is the only way to get it for 360.

No, I believe you buy them with either playstation network points, and xbox live points, each map pack is $15 U.S. You can get psn points and xbox live points by buying them through your console online, with a credit card, or b buing a points card at a store.
No. You buy the points so you can buy things on Xbox. (Microsoft points)
Microsoft points are the currency for Xbox and other similar marketplaces. They enable users to buy small items, such as platform games, without having to use credit cards.
