Is there a lot of stress on the bike when clamped into a trainer? I have a cycle ops fulid and I notice that when I am using it, my frame flexes a little side to side. Is that not good for the bike? Is it going to wear out from flexing like that?

Just from what I've read and observed---flexing is normal on a bike and you don't really notice it on the road---they are designed to take this kind of stress.

On the trainer, the flexural stress concentrations are greater on the stays, BB, fork, and headset because you are not permitting the bike to disperse the load as efficiently as on the road. You can only hope that the frame designers have added a good margin of safety in their design for fatigue loading.

Others on the forum have good recommendations to just use a beater bike on the trainer, but I don't have that option at the moment, thus the choice of getting rollers.

I just about a fulid 2 trainer. I'm more than sure Cannondale has enough safety margin to allow the bike to survive a winter training season. I hope. Anyhow the trainer feels good, and i notice the motion effect of pedaling on the bike more than one does on the road. But that would be normal. The bike riders the trainer well so no complaints there.

Question to the cycle op owners. The skewer you get with the trainer, is it good enough for the road. I mean should I switch to my original skewer when riding road and the other one when on the trainer?

I use the skewer they gave me with my fluid trainer all the time. It is fine on my cannondale. I put it on and left it, no problems, nothing, don't even notice it. It just fits well on the trainer too!

I just leave the skewer that came with the trainer in all the time with no ill effects other than it doesn't look as nice as my "real" skewer.

I always swap out the skewer when I hit the road. But then, I'm a total FRED. What is someone sees you with that cheap no-name skewer? Wouldn't you just die?
