The bars are Syncros Hardcore , and just put in there for keeping the frame of the ground (icw the fork/stem)
You have some nice kit to use as a bikestand
The Syncros post-stem-bar look good as they echo the Ibis logo colours. But I almost guess you have other plans ....
The Paul thumbies are reserved for the Fat ti, this Ibis will be build to get some serious riding so no fragile parts for this one.
Serious riding is good for you!
FWIW I have some thumbies ready to go on a rigid steel build, for use with the Jones bar (Titec one). I was not aware they have a reputation of fragility? Shifters don't get that much abuse, but this will be a rider.
