On point 2), it's not illegal to have 2 profiles one as Primary and other as Secondary applicant.
I know couple of successful candidates did the same too.
In my case, I first created EE profile with my wife as Primary applicant as she got more CRS points due to age factor.
I created another profile later myself as Primary applicant, luckily on 29th June ICT candidates were issued NOI by Ontario. So I could apply for OINP, secured nomination.
So I suggest keep all the options open, you never know which one would click though.
Hope the info helps. Good luck !!!
Thank you @CANdreams ... My best wishes to you too
