Good addons to have when in instances.

2. Omen Threat Meter
3. Outfitter for druids Usefull tool when changing gear on a druid. For an Example. you are a dps. On a speciall boss they say you are a tank or a healer.

Druids: Outfitter is a Godsend for quick kit changes between dps, tank and healing. Just make sure to disable auto changes

Gatherer: Keeps track of all nodes (ores, herbs chests etc) Shares your gather data automatically other guild members, so the more people have it, the more each individual benefits.

Additional addons I use:

Atlasloot - Lets you see which bosses drops what loot and badge/pvp gear etc (its split in 7 addons - get em all)
Cooldowncount - Puts big numbers on your spell/skill icons showing when you can use em again.
Onebag - Merges all your little bags into one big bag window.

These are all just for convenience, not ones your required to get. I cant live without them though

These three can be obtained from http://files.wowace.com/ where you also find many of the previous mentioned ones.
Dont download from other sources, get them directly from wowace since these will be the most up-to-date.
