Here we go again. I apologize in advance. When I'm trying to learn both Ruby and RoR it confuses the crap out of me..
I have looked at many MANY tutorials such as:
Buy a book. Agile Web Development with Rails. It has a new edition for rails 3.1. It’s considered to be the primer for all beginning RoR developers.

The point of tutorials such as railstutorial.org is not to show you how to develop an app like the one in the tutorial. It is to show some of the basic techniques and tools available and how to put them together. You say you have "looked at" that tutorial and others. Looking at it is no good you have to spend a few days working right through it and making sure you understand *everything* there. Then you should have a good idea on how to start building the app you want to build. You won't know everything by any means but you will know enough to be able to carry out meaningful research to find out where to go from there.
