Don't know why the booster is getting hot, with only the booster switched on and the esc off I wouldn't of thought the booster would of warmed itself up. I have a couple of the cheap £6 ebay ones and they work great despite the lower spec (5v, 1A) compared to the r/c dynamics one.
Yes you do need to plug the positive wire back in to program by the card, I only do this for firmware upgrades otherwise I just use the card as a reference and count the flashes.
