The420, I use this software:
http://www.cadsoft.de/ They have a free version for hobby / students that is extreamly powerful. The only limits are size of print area (4 x 3.2 inches) and number of layers (2) allowed. There are tons of places that will take the gerber files and create the boards for you. I have used this site in the past:
http://www.4pcb.com/index.htm and have been very pleased with the work they do. You simply upload your files to them, they check them for production problems, then send you your boards.
