Anyone know their ECM swapping?

We have a 99 Silverado and just picked up a used ECM, the used ECM came out of a 2000 Silverado..(same ECM number):

Questions:

1) Can the prom out of the 1999 be installed into the 2000 ECM, or does the 2000 prom need to be programmed for the 99 Silverdo

2) What would a dealer normally charge to program the prom

3) Can we just show up with the ECM and prom..or do they want the truck there also?


Thanks for any help
