Law schools do not care where your degree comes from as a general rule. Ultimately, what matters is your GPA and LSAT [ie. an 85% GPA from Harvard is not worth more than a 90% from Touro]. Maybe all things being equal your university/college may make a difference, but even then, your personal statement will likely be the difference-breaker.
In first year, our classes were assigned and we were not given discretion to switch our schedules. That said, there were enough people to borrow notes from and audio recordings were made readily available to accommodate those who could not attend lecture for religious observances.
In regard to living with no income, you can make it work through applying for a Line of Credit, bursaries and scholarships. If your wife is working, that obviously makes things MUCH easier. If not, budgeting will be a key to your survival off of minimum money. If you can find a cheaper place to live during those three years (such as living with family) though not ideal, that is also very helpful.
