Lightbulb Ls3 swap @ questions

I have a 99 T/A with 148k on the stock ls1. It still runs great, but I am considering a ls3 swap.
I have a few questions,
-how much would the motor alone cost me?
-would it bolt up to my built 6speed that has a 08 z06 clutch?
-what other mods would it take?-motor mounts, new wiring harness?
-would ls1 headers hook up to ls3 heads?
-would I need a new radiator?
-new ecu?

Any help and suggestions would be greatly appreciated!

the headers will bolt right up.motor mounts and radiator are fine. i believe you need some wiring adapter for the reluctor wheel being that ls3 is a 54x and ls1 is 24x reluctor. ecu may need some tuning.
