While I don't have the rules for city creation produced for the Dresden Files RPG, I have been eager to run a game in this setting for awhile and have been coming up with my own Dresdenverse Philadelphia. 

The city has Poe influence (although not as much as the Evil Hat chosen city of Baltimore), has a tie to Bram Stoker while he was writing Dracula (could be a nice Black Court storyline) which was in the same hotel that the first Legionnaires outbreak occured in (thinking of tieing that to a Black Court massacre and cover-up as well), tons of Colonial American history obviously, has ethnic-culturally centered areas such as Chinatown (to the OP point of bringing in some Eastern traditioned genre supernaturals such as Jade Court and probably a dragon), Italian Market (had already created an NPC Old god named J. Peter Dieti, Jupiter modelled after the Odin character from Neil Gaiman's American Gods), Fairmount Park (which has been called "one of the largest urban parks in the country", making it an ideal Fey ground), all the hustle and bustle of a major city with some old world feel and a surrounding area that is brimming over with history and penache.

That said I have nothing too concrete overall storywise as I want to get my hands on the official RPG stuff for background and work it in before planning, although I will only be using the Dresden Files RPG as a guide and using the d20 system as it is the only system the group I play with will use.

I just wanted to point out that Wizards of the Coast has this new community they are starting for gamers called Gleemax.  In their message to the community in general they make strong mentioning that this will be for the Gaming Community in general rather than just D&D and WotC Products and go as far as to setting up an Advisory Board which they want to be made up of people in the industry as well as fans. 

My own gaming background really doesn't cut it or add much to any type of board but I think it would be great to get someone who is really behind the Dresden RPG and Dresden Files in general involved so as we as a community have a voice.

The website is Gleemax.com, just throwing it out there.

Me likey.

Quick question though, which may answer itself as this is only part 1 of 8 but what can I say I am not a patient person.  Is it going to be explained beside taking the negative traits that go with breaking one of the Laws, how, how quickily, or if at all a Warden would be notifed of your action and be on your trail or is that going to be left up to the Game Master?

Well, first of all, d20 is a really poor system for modelling the books.  Especially the magic system.  The sorceror is a decent way to model evocation, and the wizard would model thaumaturgy.  But only in the most rough terms.  And, of course, a sorceror/wizard is a terribly inefficient build, which would hamstring Harry.

See now with my group I just tweeked the magic system in the D20 modern system to use the psionics power point pool rather than normal spell selection, and allow the PCs to cut into their HP for extra points to use for spells to show how Harry can drain himself completely when using magic. It seems to work fine for us.
