Partner Visa application submission

Hi Everyone,

I have just submitted my partner visa onshore 820/801 first stage application on a de facto relationship basis.My first question is how long would that take to get me on a bridging visa?
Also me and my partner have submitted both the our applications from the same immi account. But it only shows my application has been received but not the one my partner has submitted. As I am about to get my previous visa expired soon in next 12 days. In any of the circumstances, is it possible that I may have to leave the country as even if I have applied my visa onshore.
Thirdly, we have submitted the application only but haven't uploaded any of the documents yet which I was waiting to do in next one or two days as I am still getting all the documents ready for upload. Is that going to affect me getting the bridging visa if I upload documents in next couple of days. We have paid for the visa already.
Lastly, I am confused about form 80 for personal particulars. Do I need to submit that as well with my application???
