you are wrong
On to paralleling the transistors - yes, you can parallel them, but it isn't as simple as just attaching the leads together. Transistors experience a positive temperature coefficient in gain. So higher temperatures mean less voltage drop. With two in parallel, they won't be identical to start with so one will have a little less voltage drop, which means more current flows through it (current follows the path of least resistance). So more heat, which raises the temperature of that transistor, causing a greater imbalance, until that transistor is hogging enough current to overheat it and burn it up. Then the second transistor has all the load and also burns up.
