Hackers suck!!!!!!
Hackers hacking a server sided game is highly unlikely. What you experienced is nothing but lag. When i lost all my weapons, and my resources, i didn't blame hackers, i blamed lag. Also, with me almost beating my last time trial for my Black Dodge challenger, i didn't blame hackers either, i blamed Trion >___>
I won't discount hackers being the problem, but it sounds like that is actually just terrible lag issues. I have had/seen that happen many times since the servers started having issues. Hell, I was actually getting mission objectives in a four player instance without seeing a single enemy on my screen! The floating person thing sounds like lag as well. Just like vehicles on your screen driving through a mountain.
As far as the pvp thing goes, I'd bet on it being some weird server issue again. As I mentioned above, if I can be in my own little "reality," and still get credit for a mission, I would bet that can happen as well. Just somewhat educated guesses though.

The floating isn't hacking, that's some lag and culling issues. Happened in the beta on highly populated Arkfalls.
Don't report people because you don't know any better, people floating is lag, teleporting is lag, if you see quick 180 snapping that's hacking
