Gundam 00 Episode 04

[Yukimura]

I didn't realize this is your first Gundam series Kraco but that explains some things. It's basically a tradition that at the beginning of a new Gundam time line beam technology at a mobile suit scale is pretty much unheard of if it exists at all. Then the first Gundam(s) of that time line tend to come along and utilize beam technology and everyone else is completely shocked and overwhelmed by it until they acquire the technology themselves and put it into newer models. It's also tradition for Gundams to be significantly faster, more maneuverable, and harder to damage then any of the grunt suits they fight against unless said suit is piloted by a named character. 00 has not really demonstrated that the Gundams are as indestructible as some of the other suits to carry the name but at the end of the day this show is a Gundam show so I wouldn't expect to see a bunch on nameless soldiers disabling or even damaging any of the Gundams no matter what tricks they might have up their sleeves. And as to your comment about the dodging that's another Gundam tradition. A 50-60 ton machine being able to dodging rail gun shots or laser blasts from a few hundred meters away is par for the course assuming the pilot of the machine has a name. If that sort of thing bothers you you might as well just stop watching.

And you're right about the scene at 15:49 looking like a radar display. That scene is in direct conflict with most of what we've seen so far with Gundams and radar. Since the screen was acting very much like a real radar screen I must assume either the writers don't know how to maintain both current technological accuracy and futuristic technological continuity or the Gundams can simply turn their radar cloaking on/off at will.

As to the weapon guidance issue I don't doubt that in the future guided weapons could be made capable of switching to visual guidance depending on the situation. However I don't see any reason why anyone would ever put that sort of technology into a guided weapon. As I mentioned before it's extremely easy to fool. A visually guided weapon would be significantly less effective at night and wouldn't be able to cope with something as simple as a smokescreen, why would anyone spend the time and money to developing such a sophisticated visual guidance system when an enemy could so easily counter it? Your point that a Gundam probably wouldn't fool a visual guidance system is not a compelling reason for the militaries of the world to have paid for the R&D and mass produced weapons incorporating such guidance systems in a world where there main concern would have been potential war with one of the other super powers.
