Don't worry. You start to get a hang of it after a couple of months in this forum.

Is there a way to consolidate these?
Well!
Your DA account (that is, the one you use in the game) is nothing more than a regular EA account, and any EA account should work. Your BioWare account (Kn1ght5h4d3) is directly associated with an EA account whichever way you registered; it creates a new one if you selected a no-EA option (which you didn't, yes?). Some users have spoken to EA support and have purportedly been able to merge multiple EA accounts over a 24 hour process. Some users have spoken to EA support and have been told that this is impossible. My suggestion is, find all the EA accounts you'd like merged and speak to EA support, then cross your fingers.
What's important to understand is that all DLC is attached to your EA account exclusively, but you can only redeem codes via a BioWare account.
