how do i get coordinates to appear next to my map?

I think it's a addon, I havn't got them either so i could be wrong.

I use a combination of Cartographer and Lightheaded...it is a combination that will adjust your map settings to a window style box in the game, not taking up the full screen, and lightheaded attaches to your quest log, and will give you co ordinate links that you can click on and it will put an arrow on your screen that gives you the direction and even the distance you need to travel...

go to www.curse.com
click on WoW add-ons.
download client version of "koodinator"
install appropriately

Divide your screen up into 10000 different parts (100x100) and count from top left corner. Use permanent marker.

Or you could go to wow.curse.com
