I get inspiration from lots of stuff.... Scott Pilgrim just happens to be really big right now... 
Toronto's a nice city and I've always liked going there so I'm familiar with it, plus I used to live kind of like, right near it so when I was trying to think of a city to place it in, it ended up there. I figured going with someplace I'm familiar with rather than going with someplace like Chicago or Boston or NYC (which has been done to death and I don't really know as well) which I'm not as familiar with would be harder and possibly more awkward 'cos it's like... well, sort of like when Americans write manga/stories/etc. that take place in Tokyo. 
(Anyway, SP taking place in Toronto and its Canadian-ness is one of the many reasons I love it)
Speaking of again, I really hope you guys don't compare Wallace and Dan too much. >_<
It's kind of like comparing Eureka to Rei.
FFFF, Oh wait.
I mean, at this point it's kind of hard to tell where the character is gonna go so it's easy to see why people (Proof. >:|) could think I totally blatantly ripped him off. But I promise, he's more than a snarky gay friend. Promise.
Inspiration from stuff... well, I've been reading some webcomics like hinabn and string theory and johnny wander which helpme sort of figure out what looks good with paneling/text bubble placement and that since I'm still kind of learning. So there'sprobably some inspiration from there? Oh, style wise hinabn is a prety hueg influence.
And I think I'm done rambling now. Heh.
I totally forgot I was on my alt.
