Well, good news on the store front:
Veteran packs can be bought for 80 MSP, and Spectre Packs (60k creds, "at least 1 Rare item or better) can be bought for 160 MSP.
Also, those that played BF3 get an exclusive class unlock, and the first pack you get (the free one) usually has something good in it.
So far I've unlocked a new pistol (bleh, the Carnifax, which sucked in ME2) and an Eviscerator (this was in my free pack wtf).
my friend has a krogan and an asari waaaah
