If I remember correctly, you need to log into Dragon Age Keep with the same account that you used for Origins. It should detect your heros from Origins and import them. I don't remember if it imported my World States.... Come to think of it, I don't think it did. I ended up customizing the World States myself, then importing them into Inquisition from Dragon Age Keep.
As for a step-by-step:
1. Log into Dragon Age Keep using the same acct used for Origins
2. Customize your World State with the Tapestry
3. Export your World State using "Export to DA Inquisition" on the right hand side menu of Dragon Age Keep. Confirm that the name and date on the exported World State are correct.
4. Start Inquisition with the same login for Dragon Age Keep
5. Create a new character. During character creation it will ask if you want to import a custom world state. Confirm the date matches the export you made in Dragon Age Keep. If the date doesn't match, you need to try exporting from Dragon Age Keep again, and start character creation again.

Probably more helpful than my instructions.
