Questions about Potero Chico

My recorded comments on Estrellita: "Dec 23, 2009 O.S. w/ Jon via 5.11 P3. Good, but lots of Scrambling and not much climbing, Nor is it 1200' tall"
Pancho Villa is not really a long climb. It's 500'. But it is a better climb than Estrellita.
Will The Wolf Survive is not big either. About the same as PV. YOu could probably do 3-4 climbs like it in a day if you are moving reasonably.

The grades there are soft and the routes are not very sustained, so making time is not hard to do so long as you are not behind someone who is struggling or just slow.

I cant tell you much about TWZ or SB, as I have not done those.

I used a single 70M for almost everything there I can recall.

As for guidebook? Whichever you like for trade routes - they will do the trick. Really what you need is something that gives you directions to the base. Then you just follow the bolts.
