To answer your questions about processing time. There is a processing time line posted on
www.cic.gc.ca. In our case (out-land US via Buffalo fwd to Detroit) it took about 90 days from the day we sent the sponsorship application until we got the PR. As long as you make sure you submitt all the documents, photos etc and fill out the application correct it shouldn't take very long.
If your file outland application the applicant can travel to and visit Canada (I travelled to Canada once a week while my application was processed in Buffalo). However, the applicant can "move" there and permanently stay in Canada while waitning for PR application to be processed.
Good luck
