www.tsroadmap.com is a most helpful site also. It is pretty specific to the US, but lots of the information can be adapted to anyplace.
As far as working in the industry... remember that only a few girls do more than a few photoshoots, much less films or anything resembling a career. One thing to alse keep in mind is the stigma attached to the sex industry in many places. You can't really use a career in porn to get a "mainstream" job.
That said, the money from sex work can be used to fund your transition and/or pay for schooling. It is one of many options open to you.
