Stumbling in the dark

As a special education student, I think it is important to learn about the special education classroom and all the technology, interventions and tools that I might one day use in my own classroom. So to start finding out more about AT and how to effectively use and include it in my classroom I have joined this online network, plus others such a Twitter, QIAT and have been trying to follow some blogs as well. But as I muddle my way through all the mass emails I get from all of these different places I find myself overwhelmed and a little scared of how to use all of this information.
Even though I do have some experience working in special education classrooms and using AT devices, my education is still severely lacking. And I find myself wanting to learn more, but I am afraid to search for information and actively ask questions, and post comments to people. What if I say something stupid? What if I say the wrong thing? I find myself stumbling around trying to soak in information but not successfully doing it. There is so much information about AT out there, and I have no idea where to start.
So...any suggestions?
