Go to the Grand Exchange (northern part of Varrock), talk with Brugsen Bursen for an introduction, then simply place your offers, to buy or sell things. The basic principle is that you can buy something if some other player wants to sell it, and vice versa. So if you place a purchase offer and at that moment nobody has a pending sales offer (compatible with your price), you may have to wait a while.
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.
