newbie with rules questions

[kheisner]

I was watching a game recently and being a "new" ref several friends were asking questions about some of the calls and I am just checking my answers.

1. Are all technical fouls 2-shots? (yes) Is there ever a time it is one shot? (no)

2. Can a player come off the bench to shoot the technical free-throws? (yes)

3. In the case of a "flagrant" foul without injury....is there ever a time the person who gets fouled does not shoot the free-throws? (actually saw this happen....officials treated it the same as a "technical" and I thought they were wrong.)
