I just made a great discovery in a ArcGIS extension called zigGIS.
From their site:
zigGIS is an ArcGIS Desktop extension that allows you to connect directly to spatial data stored in PostGIS. It is a lightweight option to allow you to centralize your spatial data into the leading open-source spatially-enabled relational database.
Using zigGIS, you will be able to take advantage of the advanced analysis and cartographic tools of ArcMap while leveraging the superior spatial data storage and management capabilities of PostGIS. zigGIS will enable you to view, analyze and edit your PostGIS spatial data from within ArcMap.
The most exciting new feature of zigGIS is the introduction of multi-user editing of PostGIS data from within ArcMap. zigGIS now includes tools to enable you to check out your data and make edits with the native ArcMap tools.
Best of all, zigGIS enables all of this capability for users of ArcView on up without the need for additional middleware.

This is awesome news for me since I use PostGIS everyday. The only gripe I have is no support for ESRI (at least not editing). This is going to make my life a hell of a lot easier and data management a breeze for me. Because, currently uploading spatial data to PostGIS is a bitch of a process when going from a windows box using ArcInfo to a PostGIS database on a linux server.

More Progress
It seems that I have finally corrected any errors that were occuring that were sending Jianfei's graph out of whack. These seem to have been most disconnection errors or labeling errors. We have been running tests using the path-finding algorithm and everything seems to be working OK. There are still some errors that are occuring due to problems with how the algorithm works and deciding on using stairways and elevators. These problems should be easy to fix.
Right now I am working on incorporating different data sources into ArcScene to try to create a composite scene with the graph model, woodward files, and other GIS data layers that might be relevent.
Here are some screens of how the graph is looking and a couple looks at the incorporated GIS data in ArcScene:
This mainly shows the internal structure of the hallways and paths to get around the building. This graph is what we will use for route-finding, and we hope this will eventually get incorporated into the street networks so we can do route finding on a larger scale (hopefully citywide)
These two images show how different data sources can be incorporated into our current work. I have created 3d building of the campus and added in roads and the woodward and cameron files. These files are obviosly much more detailed, however, having this type of view is nessessary not only to make it easier to visualize, but easier for an emergency worker to find their way around.
