Kerbals with hammers doing 'maintenance'? is what comes to mind...

SHHHH! Dont tell them!

Yes, thats how acceleration works, hence the g-forces you feel if you accelerate or brake quickly in a car, but testing it in KSP will be hard, youll have to do what rodion_herrera suggest, and have someone flying, as you just have a kerbal standing there, you wouldnt be able to try walking and jumping and such, as the second you switched to the kerbal on EVA, thrust would be cut.

Will the solar panels withstand Eves atmosphere and gravity?

You keep the water, and most of the vessel in space around Mars, only a small hab module would go down, as the Martian surface aint exactly welcoming, so a small bulldozer could easily cover a large portion of it with dirt, further reducing radiation. Seeing as they would need only a fraction of their water supply to be on the surface with them, it would make to sense to send it all down, plus Mars does have a thin atmosphere which would help cut radiation as well. As for the eyesight stuff, some of the astronauts that went to the moon reported seeing bright blue flashes with their eyes closed, NASA thinks it was caused by cosmic rays passing through the optic nerve. I cant recall if it was passing through the Van Allen belts, or afterwards. I cant imagine that. 'Uhhhh, guys I think Im going space crazy. Im seeing bright blue flashes with my eyes closed...' 'YOU TOO?! I THOUGHT IT WAS JUST ME!'

Economically? Yes. Practically? No. To shield the crew, tanks of water/metal plating could be used around the crewed sections of a ship, but all of that is very heavy, as for surface radiation, covering the landed sections with dirt is a great way to cut down radiation, and protect if from wind born particles that erode stuff like sandpaper. However, all of those things add greatly to the already substantial cost of a mission, all for very little return, as robotic exploration has been very fruitful, and will likely lead to sample return missions. Robotic missions are also a fraction of the cost, allowing several to be mounted for the price of a manned mission, meaning either more sites can be visited using a similar robot, like Spirit and Opportunity, or be a specialized mission like Phoenix. TL;DR that level of radiation wont stop humans, although it would complicate things, rather other factors are stopping us.

Truly epic.

Hahaha, I love it! I cant wait to read more, keep it up.

Awesome that Jeb survived, you may try using your nuclear engine for most of the landing with a quick blast from the others right at the end. Also, sick carrier plane!

Delta-v calculations, or calculating altitudes for aerobraking, to put your apoapsis at a certain altitude.

Random failures being implemented would make me rage so hard. 'Oops, your height above ground was actually in feet, while your speed was in meters per second, haha, our bad!' 'Yeah, turns out we didnt use the proper length screws, so that power generation block for your Vall rover? Gone.' 'Hey, random oxygen leak, all your Kerbals are dead.'

'Wait, wait, wait, you mean you want to detach, and pull a 180, IN ATMO?! Man, screw this, Im outta here.' *ASAS disconnects from rocket, rocket makes it to orbit with out it, and the RCS ports it had....*

Its a pain, but its doable, often it will take several attempts to get them all to stick, if they dont all latch, just undock, back away a few meters, and come in again, eventually they will all latch, it just takes a lot of patience, and sometimes luck.
