Hi ashregina
One thing is for sure DONT APPLY ANYTHING EXCEPT PR AFTER MARRIAGE. Its not recommended at all. Even before marriage if your wife has a visitor visa or work permit its gonna take almost double the time had she been in india. Moreover, if your wife's visitor visa is rejected it will delay the application for PR as well..If your wife has a travel history then it will get delayed as well.
The process is very simple...I made biggest mistake as i didnt go India prepared and it took additional one month for me to apply..our case was almost finalized before the strike started...every single day that you delay after marriage will count towards end. Just download all the documents from site cic.gc.ca/english/information/applications/fc.asp ..there you will find IMM3900 guide that will help you how to fill the forms..part 1 are sponsorship forms to be filled by you..part 2 is PR application to be filled by your wife (you can fill it too)...you go there and get signature from your wife on forms ..keep multiple copies of signed forms and you can fill them after you come back to canada...
Collect as many marriage proofs as possible..keep expenses receipts..get affidavits from people travelling from abroad to your marriage ..get affidavits from renowned public figure, etc..keep air tiockets, boarding passes, dont miss a chance to click pic when you were together before or after marriage..etc..
