1. Colonel Blood is a character, and he says "You wouldn't have wanted to be in Colonel Blood's shoes" (though it is hard to hear the "s") This means you dont want to be in his position or be him at the time of these events.
2. I believe he is saying "dastardly daring" which means dispicable, cowardly and malicious, etc.
3. "You follow" is a way to say, "Do you understand what I just said?" Someone may also say "Do you follow?" as an independent sentence while explaining something to you in order to check if you understand.
Did you follow that? ;-)
