I have a 360 that is a core edition one, but with just an added 64mb memory slot-in thing. I also have a computer connected to the internet. How much would it cost to "liveify" my 360 in the first place (e.g. what would i need)? Does it depend on what interent connection i have?

Also, what are the exact adventages of getting xbox live gold, and how much does it cost /year? How much time would i be able to spend playing games over live, with normal computer internet useage and a 2gb/month download limit, or is that not really possible thanks if you can answer any of these questions for me...

It doesn't cost anything. You just have to have a broadband connection and plug in your ethernet*sp* cable to your ethernet port on the back.

Xbox Live Gold=$50 a year.

Xbox Live Gold gets some demo's early but the big advantage is you get to play online whenever you want as opposed to the special weekend thing with Xbox Silver.

Also if you want to get demo's you would want a hard drive which is between 100 and 200 dollars depending on if you get 20 gb or 120 gb. (20 would probably be adequate for you)
