The first Runescape player to say g.e. for grand exchange was WEEDYMUN.
Much of the trading in RuneScape is done via the Grand Exchange. Go there, and talk to the Grand Exchange Tutor, to get started. It is also possible to right-click on a player, select "Trade", then exchange items with that player.
No, it's only in the main Runescape the Grand Exchange was made.
There is no special "Grand Exchange account". You have your RuneScape account (just log in normally); you go to the Grand Exchange and start buying and selling things. First, you have to talk briefly to the guy (NPC) with the megaphone, south of the Grand Exchange. This is once only.
Go to the Grand Exchange and buy one, or buy one from another player.
You find shears and the General store, buying from another player, or the Grand Exchange.
