How do I identify which transistors are which?

There is text printed on the transistors. To make it easier to read, you can take a photo and zoom in on that text.

What are the forward voltages for LEDs?

LED forward voltages vary, but most are in the range of 1.2 to 2V at around 20mA. However, white LEDs work at 3V+ and are typically overdriven blue LEDs.
