Classic Specific Addons

If you are just coming back to WoW after a hiatus, this is a good place to start. These addons provide some needed changing to how the game functions so that you can make your most informed decisions possible when adventuring in Azeroth.

CLASSIC CASTBARS -This one is pretty straightforward. It gives you a castbar on the target frame, and below the name plates of your target. It's very hard to interrupt on time without this. It's very very combat effective with a small caveat - it's not always accurate.

CLASSIC LFG - This one is pretty crappy so far, but it depends on more people downloading and use it to become effective. But whatever, go ahead and keep spamming /4. This mainly functions was a way to easily connect you to those running groups. You still need a warlock with a soul stone, or to walk your happy ass to the dungeon's entrance.

REAL MOB HEALTH - Cannot skip this one. This keeps a database of every mob you see and tracks it's health based on the numbers it took for you to kill it in combat logs. It sometimes take's 1 or 2 tries to get a read, but then it stores it for future use. ZPerl actually picks this up and floods the data into it's frames, so it will help you greatly.

FASTER LOOTING - this addon removes the awkard autoloot delay. I use this and have enjoyed it, although for it to function it will tell you every time you loot a unique item that you can't do that, even though it's already in your bag because it's command spamming.
