Where to begin.
I agree strongly with slitends about talking to a professor. Such a conversation would help answer your questions and would also give you a person to ask for a letter of recommendation when you apply for graduate school.
I would really take time to consider what piece of urban sociology to which you are drawn. It is a pretty broad field. Inequalities. Environment. Planning. Policy. Really, anything. Education in an urban setting. Gender and sexuality in the city. So so much. Once you are able to narrow the field a little bit, making decisions will become a lot easier.
As far as being in a slump, you do have to do something. I mean, whether you decide to enter the workforce or continue on with academia, something will happen. I don't think that choosing graduate school when you are unsure is a bad idea at all. If you hate it, you can stop. If you love it, you can continue on. If you decide you are interested in something else, you can go for a different degree.
As far as applying for places with funding, you can apply for a PhD program that isn't as academically focused and consider it as an option. If you decide not to go, you can leave with a masters degree. That isn't a terribly popular option, but it is an option and it will give you more options.
Also, check out the articles in City and Community (ASA publication). The more recent issues should give you a good idea of what is going on in the field.
