Tips for Quebec City & Montreal?

Help a girl out. For our upcoming anniversary, we'll be in Quebec City and Montreal. Any cool tips to share?
I've been to Montreal about 20 times since it's only a 4 hour drive, but we're always there visiting friends, not really as tourists. I've never ventured far out of their neighborhood (near Atwater market), Old Montreal, or the downtown area, but since we are spending the first two days alone, we're going to explore a little so I'd love some help.

I'm looking for vintage and modern home stores, good eats, clothing consignment shops, Japanese shops (for zakka, magazines, books, CD's), bakeries, sew shops, and fun little districts where there's a heavy concentration of coffee houses, eclectic shopping and galleries to cruise. (I have a few city links for Montreal in my right column, but I'm willing to beef it up to benefit all if you care to leave links.)

Anyway, thank you in advance for any fun tips you may have. Oh, and we leave on Thursday and will be in Montreal for the first 5 days, then it's up to QC until the following weekend. I've never been to QC, so I'm completely lost when it comes to what's what up there. Of course, there are a slew of travel sites, but I'd rather hear it from my friends, so please share! :)
