Addons
I would first off suggest downloading and installing curse client. It is a program that you will be able to search and download for wow. It installs them automaticly, and alerts you if an addon has an update, which is pretty much weekly for some of them, and that helps you keep from having crashes.
Curse Client Download
Addons to search for with Curse Client:
Deadly Boss Mods:
When in a dungeon or raid this addon alerts you to what a boss is about to do and gives you a timer for how long it lasts.
Adds 4 extra bars that you can customize to any size and placement. The 4 bars are stand alone, so they don't use your current bar space so it really is EXTRA bars. They also change with dual talent spec to whatever you had them loaded for.
GatherMate2:
This addon shows you where known nodes are for herbalism, mining, and treasure chests on the mini-map and normal map. Also to make it useful instantly you will need to download the optional GatherMate2_Data, Otherwise it will only show nodes that you have collected since you installed the addon. There is also an addition, GatherMate2_Sharing, that will share nodes you find with guild members who have the addon.
HealBot Continued:
This is a healers BEST friend. It adds a window that automatically changes with your party or raid size. This window shows peoples HP Bars, and they are clickable. With Numerous button combinations with left and right clicks you can click to heal anyone in your party or raid with ease. The Whack-a-Mole game just got easier.
Recount:
Brings up a window that shows DPS, DMG, Heals, and various other information about what your party or raid is doing to mobs. So you know if you're the weakest link.
QuestHelper:
Tells you how to finish your quests in the quickest, and easiest manner. Has a database of quests, monsters, and items. Also computes the fastest path to complete all of your quests, and gain xp as quickly as possible. The new wow quest log is almost up to par with this addon, but not quite.
