Can't find serial from PSstore!!

1) Game code itself contains information about CE or not CE, so you can't separate the CE items and put on your 1.0 if you want to also have a different account for the PS3. That is, there is no separate code for the CE items.
2) I'm not sure you need any codes at all if you buy from PSN.

referring to 2, this is correct. all of the items are automatically put into your ps3's thingy to be ready to use.

edit: also aren't people able to upgrade their existing accounts to CE to get the items?
