KSP includes a "Debug Menu", which you can access with Alt + F12
. From within this menu there is an option to disable gravity. Once gravity is off, go to the Kerbal you need to save and use the EVA pack to gently lower them to the ground.
You can read more about the Debug Menu here
Repairing Spacecraft
No there isn't sorry.
At the current state of Kerbal Space Program, whatever you do to your ship is final.
A good way to "repair" the ship, is to put docking ports on every part of the ship, and dock it together during assembly. This way, if for example, the left rocket breaks, you can send a new one up, detach the old one, and put the new one on.
Currently this would be classified as the "only way". (As of Beta 1.0)
"Re-inflating" Spacecraft
So Spacecraft cannot be "repaired". But they sure as hell can be re-inflated!
By this I mean that if a tyre pops, for example on a rover, then you can get a Kerbal to EVA up to the tyre, Right Click the tyre, and "repair" it, which re-inflates it, fixing it. (As of Beta 1.0 you need an Engineer with the correct rank to do this.)
The same can be done with landing gears, and re-packing parachutes.
Currently these are the only things repairable. (As of Beta .90)
Engineer Ranks:
Level 0 engineers have no special abilities.
At level 1, they can repack parachutes.
At level 2, they can repair wheels.
At level 3, they can repair lander legs.
They gain no further abilities with additional levels.

Repairing the KSC
Sure, buildings can collapse and be destroyed if enabled upon save creation, but repairing them is even easier. Just Right Click the building of your choice, and a "Repair" option will appear. Warning: This feature will cost money if you're not in Sandbox

Never did that before, but I think you should be able to do it by manually editing the saves files. More precisely the
persistent.sfs
file.There is a
ROSTER
category located somewhere down the file where you can find all your crew members. (Lookup their name!)You can revive them by setting their state back to 0.
(Seems to be confirmed by http://forum.kerbalspaceprogram.com/threads/41891-How-to-revive-the-%28bob-bill-and-jebediah%29)
You can as well add Jebediah to the command pod. Lookup the ship's name into the file and locate the
crew = x
value. Change this to the number of crew member you want to add. Jebediah should be 0.
