Rumor is that the DVD will see release in late September, perhaps even the first week of October. Most movies hit DVD in 3-4 months now.
As for 3D, there are different types of 3D tvs.
I normally don't recommend this brand, but at the price, I can't complain...
Wal-Mart has a 32 inch Vizio 3Dtv for $498.00
It comes with 2 pairs of glasses, and uses polarization, the same technology as Real D, which is what's used in theaters and the Optimus/Bumblebee masks. All you need is that TV, a 3D Blu-Ray player ($150.00) and the movie in 3D.
I'm sorry to hear of your condition. I hope your good, healthy days outweigh the bad. I'm really sorry you're suffering.
