Practice together. A lot. Learn to be comfortable sticking *very* close together.
Understand the relative strengths of each rider. Practice giving the strongest riders slightly longer pulls. If there's a weak rider, make sure he understands it's OK to do nothing more than pull through. Make sure your strong rider(s) don't try to be heroes and excessively ramp up the pace during their pulls. That's death to TTT. Learn the maximum sustainable pace, and stick to it. Only push it in the last few miles, where it's OK to drop the 4th guy if necessary. (I assume)
Understand the course. Understand if there's a wind direction change on the course due to a turn, etc, make sure everyone knows when and how to change the direction of rotation. It should be clockwork. It can be good to assign a captain who calls out commands for changing direction, etc.
Communicate. If someone's struggling, you don't want them to suffer silently than disappear off the back too early without anyone knowing. Yell "down."
This is great advice. I would certain advise a couple practice rides together in a tight paceline, even more so if all are racing the TT rigs. Having a team captain calling the rotation is a good idea as well. Worked well for myself and a couple teammates recently.
Good luck!
