I am agree with our friend Egiman
the better option is to include your wife within the application, let's say that you apply today, so after may you should send an update to CIC in order to include your wife on the process, or just wait until you get married and then apply for both at the same time. (I think it could be better)
if you don't apply for her now and you decide to do it after you get the PR, She will have to wait in your home country until she gets the visa (it could be months or maybe years after your landing at Canada).
now about the simplified process, I think this is the new process I guess you will be asked to fill just basic information when you apply and then CIC will start asking for more documents along the process (if I am not wrong)
I did my application on the old process, and let me tell you my friend, it was a bunch of formats and notarized documents requested at once.
Now, the faster way so far as I know is applying through PNP or getting a permanent job offer
