Destruction improves the direct damage spells of the Warlock.
There are also talents to increase the speed at which your pets attack,
as well as to improve your damage-dealing spells, their chances to
get critical effects, and the damage done when critical effects occur.

Spell Hit Cap:
Spell Hit Cap = 202
4.1 - Spell Hit, Crit, etc.
The Numbers above detail the percentage to which each point of +Spell Damage actually effects any given spell. For instance, 1 point of spell damage does not automatically equal an increase of one damage, rather it will increase it to a percentage as listed above.
If the spell you're looking for isn't listed above then simply take the base casting time(without talents) and divide it by 3.5. However, a different formula will apply to AoE spells.
What to shoot for when entering Karazhan & Heroics:
If you simply want to make certain you're good to begin attempting karazhan and heroics try aiming for the stats below as an absolute minimum, surpassing them however is recommended to make things overall quite easier.
Additionally, you can downgrade these stats somewhat for the easier heroic dungeons as Karazhan is definitely more challenging than most if not all of them.
These numbers should cover you for passing Karazhan into the 25-man raiding content, statistics such as spell hit will be notably harder to achieve prior to gearing up in Karazhan & Heroics quie a bit. Otherwise if you have this or higher by the time you eclipse Karazhan you'll be fine.
Note: As this is a PvE gear guide I'll only list
the PvP rewards capable of being obtained via Honor, arena rewards
are however viable alternatives to many pieces of gear.
Many pieces of gear will be equally useful to all warlocks, given that all builds utilize basic core abilities such as shadowbolt and thusly benefit from the same stats for the most part.
Once you have the right plan for how you want to play your
Warlock, consider a full blown Warlock leveling guide to get yourself
to 80 as quickly as possible. Among other things, this will
let you get into all that juicy endgame stuff just that much
sooner.
