Jason,
From what I have read and as per research, I think you shouldn't worry yourself too much about the normal things they are asking for: these are quite normal things they ask proof of. I am sure if you can satisfy them regards whatever they ask for, you will get the PR Visa soon.
For proof of fund, just get a statement of account from your Bank or otherwise show equivalent of required amount (Depending on the number of people) converted into Canadian dollars.
Out of all what they have requested the only thing that may be a cause for alarm is:
"Letter stating i have broke up with common law", as I personally would not understand how this is supposed to be verified but again if they need a letter only from you. Then, write one and give it to them.
Fingers Crossed!!!
Best Wishes!!!
