Not anything near Earth's orbit. Anything entering from outside and headed straight for Earth. Since escape velocity is the exact velocity Earth's gravity can cancel out for something headed straight away from Earth before it leaves our gravity well, it is also the velocity it can add to something headed straight for Earth. That makes sense since it is the exact same force. Most things that enter our gravity well do not pass straight through the center of it of course. Earth's gravity will still accelerate these things towards the center of the earth, but this will just curve their trajectories a bit for the most part.
Decaying orbits do not have a lot to do with escape velocity. That's as far as I understand it mostly the moon's gravity fucking things up. A Lagrange point is as you say a point in orbit where for example Earth and the moon cancel out eachother's gravity so your orbit will not decay. This is however still well within Earth's gravity well (which is huge). An orbit is just being in a gravity well and traveling at less than escape velocity.
No problem! If I see an opportunity to use my Kerbal Space Program addiction for something productive, I'm taking it. I just hope I'm not coming off as too insane.
That was just meant as a quick joke about how if I'm on the same sanity level as everyone else here I am clearly insane. Thank you for your concern comrade, but I'm actually having the time of my life rambling about orbital mechanics with everyone and this was not really meant to convey insecurity or fear. It might have been in bad taste, considering that people actually do share real problems and concerns here. In that case I'm sorry, otherwise don't worry!

Oh... Ok. Should I deal with that somehow?
