as someone with a physical disability who's been in web development for 15 years, I can tell you from personal experience, your disability and the ability to land a job are totally irrelevant from one another. Your ability to code and develop applications is what will land you a job.
My current job, which I've been at for 2 1/2 years, is only somewhat accessible. I say somewhat because there is a flight of stairs that are the only way up to the office. On my interview, it was clear they were going to offer me a job, and when they did, they asked me if I needed any accommodations. The first one I asked for was a railing on the stairs, which would make it that much easier for me. The second was the ability to work from home when my body was having an "off" day. I explained what I meant and they had no problem whatsoever allowing me to work from home when needed.
I tell you this because other jobs have offered me the same thing, as it's common. They knew in order to get the skill set I bring, they would need to provide me with "reasonable" accommodations, which is actually a legal requirement if you live in the US.
As for resources to what to learn and how to learn it, others have provided excellent answers. Don't forget Q&A sites like StackOverflow and ExpertsExchange are great tools as well for learning.
Don't look as your disability as a hindrance, but rather just another part of who you are. If people don't like it, their loss, not yours :) If you have any specific questions, feel free to post here or message me privately!
