how heat resistant are these components?

[lightningfingers]

diodes, transistors and opamps? how much heat does it take to kill them all together?

Solder as quickly as possible.  Use sockets for ICs if you can (saves a lot of heartache).  Some socket trannies but I don't bother.

For diodes and trannies I attach croc clips to the leads to sink some of the heat.

'Not very'..heat resistance.
 More like sensative to high heat.
 Yupp...sockets and alligator clip/heat sinks are recommended.

This is no general rule as too how much heat components can take. Some can take more some can take less. I prefer to socket mosy of my transistors, IC, etc. so the heat goes on the socket not the component. As for operational heat lets say that most parts can take more heat then you can.
