For the strength enhancement, as it states in the writeup this is not very significant. The strength enhancement is more of a minor side effect of the layers purpose as emergency splint and backup to the bullet-resistant layers.
As a generally comment to the other points, those aspects of the suit are effectively unchanged since the previous attempt at getting it approved and at that time you yourself said they where perfectly acceptable (the issue was the electroreactive myomers. If you would like the link to where the US army is actually using this material in the Future Force Warrior armor, I can provide it. Again). As has been stated many a time, the Lorath are very close to Yamatai in many fields of technology and all areas that would relate to making a suit such as this could quite feasibly be worked on while underground.
The repair capability has more to do with the interior layers, since it could only fix the TiS2 layers very slowly (and then only moving the threads back into position) since it cannot affect them very easily at all (and where they not micromachines, not at all period, the bonds are too strong). The primary purpose of the system is maintaining the user (you will note that is what most of the length of that segment is about).
It is fairly easy to block projectile weapons, EMP, & sharp objects (the IRL material Spectra [Duneema] is quite capable of blocking knives) with the current tech. And as I said it cannot stop very high energy long arm rounds (such as the mentioned M12, which I am still working on, it will be posted soon).
High-energy radiation is blocked primarily by the high-density gel and the armor panels, while slower radiation (alpha & beta particles, slow neutrons, etc.) are stopped by the other layers. Because the suit is designed specifically to prevent after-effect radiation (where the material itself becomes radioactive) it can prevent one of the more dangerous aspects about many radiations (i.e. that they are persistent, continuing to damage the user even though the primary source is gone). This is achieved using very stable materials.
By protecting from jolts I meant minor ones and mitigating larger ones, I do not mean it could protect totally from falling 6 feet and landing on your back.
