I think this thread will help you a lot!
In short, no, your file is not close to complete. I had the exact same situation (ADR for spouse addition) three weeks ago, and right now my spouse's medicals are pending assessment, and I heard it could take 3-5 months for this step!
I merged (combined) all the documents in one file, and reduced their quality to meet the 5MB standard. I didn't submit any webforms, I was requested to submit directly through my cic portal.
We did an upfront medical to speed up the process.
I have heard others only taking 2 months with this add on process.
Fingers crossed
