Well, let's see if I can help.....
Obvious Tourist Stuff:
-- CN Tower. Kind of pricey, but it's kind of a "must do." Great views of the city and worth the time. Go early in the day.
-- Roger's Centre for a Blue Jays game. If they're in town, it's a great way to spend an evening. (If for no other reason that seeing the stadium)
-- Bata Shoe Museum. On Bloor St-- one of the more interesting museums in Toronto. Worth a look see.
-- Casa Loma.
www.casaloma.com A little out of the way, but very cool and worth a visit. Great views of the city as well.
-- Kensington Market. Shopping market and more west of Chinatown. Be sure to visit on the weekend, as it's pretty desolate during the weekdays. Speaking of which...
-- Chinatown. There are actually eight on them in the city, but the main one is centered on Spadina. Not as big as SF's, but worth a visit.
-- The Islands. Take the ferry out to Hanlans or Centre Island. Nice beaches and a great way to spend the day.
Avoid:
-- Paying the admission to the Royal Ontario Museum. If you are up shopping on Bloor, definately check out the architectural marvel that is the new building BUT half the galleries are not even open. At $20 a head, not worth it right now, IMHO.
Shopping:
-- Bloor St, Queen West and West Queen West are all cool areas. Eaton Centre is a very nice mall with tons and tons of stores.
Dining:
Pricey in TO, but there is always pubs, Asian restaurants and Pickle Barrel. If you are looking for a good meal, I've got some places I can recommend. Right off the top of my head: Xacutti on College near Bathurst (Indian fusion).
"Family" stuff:
Most of the bars/etc are centered on Church Street between Alexander and Bloor. There is a small area of new bars in Queen West that are cropping up as well. I love Woody's and Byzantium. If you head into Woody's, tell the bartender the Michigan Boys sent ya.

(We are there too much, clearly). Nice eateries in the area too....
If you have any other questions, I'd be glad to help!
