Here's a rundown on multiplayer unlockables... also known as weapons, equipment, perks, streaks and wildcards.

PERKS (unlock levels below)

You can select up to six perks, but then will lessen the amount of customization you can do to your weapons and equipment. The default is three perks for your class (one for each slot) and wildcards will let you choose another one perk per slot. This will use 9 out of your 10 allocation points though, so do this and you will only get one weapon with no attachments and no equipment. If you're going to use all six perks, you better be sure of it!

STREAKS (unlock levels below)

Scorestreaks have replaced killstreaks in Black Ops 2. You can earn them by kills, assists and completing objectives. The maximum number of scorestreak rewards you can equip at one time is three and your scorestreak will go back to zero when you die. You can referesh your rewards on each cycle of scorestreak system while playing.

WILDCARDS (unlock levels below)

As above, you get 10 allocation points to use on weapons, equipment and perks for each class. If if you want to have six perks then you will need to use three wildcards, which will leave you with one allocation point (each wildcard costs two allocation points).
