Read "Making Ideas Happen" by Scott Belsky. I am in the same position as you and have picked up some wonderful ideas from that book.

First: Nag, nag, nag! You say nudge, I say NAG! Nagging works as people just want to get you to shut it and they know the only way to do that is to get the task done.

Second: Are you absolutely clear in your goals and have you assembled a team which is aligned with those goals?

Third: There's the old adage of hire slow and fire fast. If you have done everything with one of the team members to get them on board and they still refuse to align with the team goals then you must let them go.
