Ooh, I love the smell of nerdy debate in the morning. It really sets me up for the day :-D

Who decided that the ideal mecha to fight giant monsters should be human-shaped? We couldn't research anything better for fighting in the ocean? Did humanity really think the best defence against kaiju was punching them and occasionally using secondary weapons as an afterthought? Why aren't they bristling with guns and other weaponry when we've seen how effective (from the original monster attack, that one jaeger with a chest o'guns etc) they can be?
It seemed that those secondary weapons were most effective when the Kaiju had been weakened by blunt force trauma or other attacks. They seemed to most respond to simply being battered down or sliced up rather than being shot. I give you the humanoid design thing, but they seemed to be mostly at home in the water. Humans synchronize best with a humanoid shape, so the human design is what you have. And the human design isn't great at water. That's why the final attack was considered crazy.
At one point a Kaiju is wounded by a
flare gun to the eyesocket. Perhaps not critically, but enough so to feel the pain and take notice. From my recollection this particular Kaiju hadn't engaged in any battle before that point (due to its special ability - I'm sure you remember the one I mean, to avoid posting spoilers for those who don't) and hadn't sustained any blunt force trauma. From this, we know two things; the monsters have pretty big, obvious and easy-to-hurt weak points sitting right in their giant faces, and that we can damage them with firearms. Even if battering with physical attacks is the best way to slow them down, why does the jaeger program not double-up on everything? Every robot battle is attended by a fleet of helicopters, yet nobody seems to have thought to load them up with missiles and have them rain fire down on the Kaiju after the jaeger lands a few solid hits. Hell, the jaegers are big enough that - even accepting the whole psychic-link control mechanism - you could add firing stations separate from the main systems where gunners could sit, not a part of the two-person control scheme but entirely independent, and blast missiles or machine guns whenever they see an exposed weak point.

Why is the jaeger program wholly reactive rather than constantly patrolling the dimensional rip? Hell, why isn't the entire area a mess of warships, submarines, giant robots and weapon platforms?
Maintenance. Having huge mecha constantly completely immersed in sea water is probably hellish on the Jaeger. You need a base to maintain and repair the thing. Conventional troops just get slaughtered.
A base like an aircraft carrier, say? Or a bigger ship built to purpose? Hell, with the resources which should, if not for the artificial stupidity enforced by the movie on the governments of the world, be available you can afford to build artificial islands and bases to sit around the rip. Any kind of early response system has got to be better than the whole world twiddling their thumbs until a Kaiju appears off the coast.

Why are the defensive walls built to keep the kaiju out so piss-weak, and apparently unarmed? Why did nobody think to copy that giant gun from FFVII and just plop it on top of the wall, aimed at the sea? Why did nobody think to litter the rip with mines and depth charges, and do the same with coastal areas aside from specified shipping lanes?
They did seem to be armed, just not well enough. I always attribute to the existence of the obviously inferior wall to some kind of military industrial complex shenanigans, since it makes NO FUCKING SENSE otherwise. Some of the kaiju would probably just fly over the mines and defenses anyway. They're assholes like that.
I didn't get the impression that the wall was built to be inferior; more that the materials to hand just weren't strong enough to do more than slow a Kaiju down. However, that still doesn't explain why it performs no task beyond keeping them out when it could be fitted with missile batteries up the wazoo. I grant you that some Kaiju would fly over the walls (which is why you also put anti-air defenses on them), but they aren't going to be able to fly over sea mines which litter the entire ocean around the dimensional rip. If the entire area can be booby-trapped, any monster coming through is going to be swimming into a minefield. Perhaps it won't kill them, but by the time they come up against a jaeger or non-robotic defensive force, they're going to look like a battered old suitcase that just fell off a moving train.

Why is everyone celebrating at the end because they destroyed the defensive rip even after discovering that the pan-dimensional conquerors can make another at will and will more than likely be coming back?
I think the idea is that the invaders are sort of a path of least resistance type, and well just kind of say "Let's go where they don't have giant robots for a while" at least giving humankind a reprieve.
They don't really have that luxury, though. The film itself states that they consume everything at a current location before moving on, and the Kaiju attacks are the
second time they've come to Earth. I get the impression that if they had any better options, they'd have tried them first without resorting to see whether Earth had become habitable yet. That's a risky move, and one you don't take if you don't have to. If anything, it seems like they'd be
more desperate to conquer Earth, and the next time they'd go for massive overkill rather than the lazy, slow invasion they tried in the movie.

Humanity is so fucking dumb in that movie, they deserved to get wiped out.
A whole bunch of stuff doesn't make much sense, but perhaps these justifications I just ripped from the depths of my colon will help you.
Well, not really, but it's fun to talk about!
