As far as 1) goes, yes. That happens to me every so often as well.
Just take manual control of your camera for a second (default command is Right Click + Drag) and it should fix itself after you've moved it.
Devs would like a concise list of things that are broken and not working currently, so here's a short list for PvP: Neutronic Torpedoes, Ionic Turbulence, Surgical Strikes (including Faeht firing through cloak), PartGen stacking and CrtH being boosted to absurd levels.
While players tractoring someone may be the cause, I have often found a weird bug most common in stfs but occurs sometimes in pvp where you gravitate toward your target and are unable to turn, unselecting it will regain control of your ship. Often happens right after death but sometimes it happens without actually dying.
#1 happened to me for the first time today. I almost puked - going to take some Excedrin and see if I can recreate it. Doubtful, since it's never happened to me before - hadn't happened since this thread started until just now either.
It wasn't the close shot where the camera didn't know what to do - it continued even with distance between the target and myself. Camera just totally spazzed out...meh.
I'm just another poster on the forums with my own ideas and opinions.
