Better tutorials and KSPedia coming in 1.1, so there's that....Also there are many ways you could learn than just watching videos. As for rival space agencies and other stuff, not anytime soon...
IMHO this would just really complicate things, especially the end of the world and the ability to control forces of nature and building kerbals. Also some of your suggestions, I dont really get...but that is just me...
That is why you deorbit your old satellites and debris from your launch...Plus, with orbital decay, if you have a lot of crafts in orbit, you would have to regularly keep tabs on your crafts orbits...
I dont think moving the lander itself is an option. Remember she is outside on EVA...Maybe just jump, climb up the ladder, etc. like what the others suggested...
