Intentional Foul Situation

[joetip30]

This is something I saw missed in a game the other night and I wanted to doublecheck!

A2 is on break and has uncontested layup. B3 comes in and undercuts him violently, U1 calls intentional foul. A2 makes the layup in spite of contact.

I believe the correct call is one free throw for the foul, then A has the ball on the baseline for a spot throw in nearsest the foul? Am I correct?

Also,

B3 fouls A1. A1 swears at B3 during dead ball situation. R gives A1 a technical foul and it is A1's fifth personal. Now you have a false double foul situation. But the shooter on the original foul has just been disqualified.

Does the incoming sub shoot A1's free throws?

Then B team gets 2 Tech ft's and ball at division line?

Thanks!
