Ken,
I like the the wheels you plan on getting for your Fit. I think if you want to use 205/45/16 tires you need to buy different offset wheels for the rear wheels. You might want to try +35 in the front and +44 in the rear. If you go with 195/45/16's on all four 7J/16 +35 wheels you should not have any problems except you may scrap your exhaust going into your garage.
The stock 15" wheel (6J/15 +53) has 129mm of the wheel towards the brake and suspension components and 23mm of the wheel away from the hub and towards the fender and bumber bracket and screw. If you use a 7J/16 +35 wheel the ratio is 124mm/54mm, a 7J/16 +44 wheel has a 133mm/45mm ratio.
I think the 7J/16 +35 wheel is better for the front and the +44 offset would give you more space to use a wider tire without rubbing in the rear. I'm not sure about availability and I know the site is in Japanese but the link below list the wheel you wanted.

Hopefully you can source the +44 offset rims in the PI.
If you have some time take a look at some of the recomended wheels for the Fit and other compact cars in Japan click on the links below.
