Macros

Macros make things easier
If you type /macro you can name your Macro Loc and give it the nice ? icon then hit Okay. Then type this
/script px,py=GetPlayerMapPosition("player"); px=floor(px*1000); py=floor(py*1000); px=px/10; py=py/10;DEFAULT_CHAT_FRAME:AddMessage(format("%s: %s, %s",GetZoneText(),px,py));
In order to use the macro just pull it off like a spell from your spellbook
When you use this macro you will be given the zone name and location coordinates even without any add on!
Macros can help you out in fights by setting focuses for re-sheeping, announcing actions, or informing the group about danger to yourself. They can even give you one button that you can hit to cast many spells. Macros can be used as a very powerful tool so just play around with them.

UI- Use Interface
This is basically a crafted collection of Macros bound together with some nice boxing. From this you are able to heal players with preset spells, view maps with saved information, have all the auction house information shifted threw in moments then listed by remaining time, etc etc etc
Some suggested UI add-ons are CTRaid, Auctioneer, and Healbot for removing detrimental effects quickly.

With macros and a few UI add-ons you will be able to quickly react to the events in game but remember that a player plays---add-ons don't.
