Pull the fiber in after you have the innerduct through the conduit. Just don't lose the pull string inside when you do it.

......and no matter what Hal thinks, use a swivel on all pulls to keep the "piggy tail" effect on the cables, especially the fiber, from happening.
Yes, pull the innerduct with the 25 pair, then pull the others at the same time....or put in separate innerduct for the fiber and the Cat 5.
Yes, use swivels ... pulling after the fact can cause sheath burn...yes, but what do you do once the duct is full? In the real world it is roded, roped, and pulled...with many different techniques, depending on the situation.
Yes, I've pulled cables into duct banks with line trucks, even stood a line truck on the outriggers and rear duals....and didn't damage any cable.
Anything else?

In a 4" conduit we would pull in three 1.25" innerducts (with pull rope), Now you have the option to make three distinct pulls whenever you want.
There was also a set of "socks" (I can never remember their name) that you could pull in instead of a hard-sided innerduct.
