Hello party people. Just switched over from iOS after 5 years to my first ever android device (Samsung GS3 on v4.0.4). Loving the shit out of it so far, but I'm ever so slightly confused by what can be a few rudimentary things (hopefully!). Sorry in advance for the long post, and thanks in advance for your help! 
1) Earlier today I noticed superuser constantly giving access to "shell". What/why is that? Oddly enough it also kept making my music start from the beginning over and over! :S I've attached a screenshot of the su log.
(Yeah I've rooted even though I'm a noob. Hardcore droid friend told me it was a good idea if I wanna install custom ROMs at some point, which I do plan to do).
2) Is there a way to prevent notifications from interrupting music playback? Every gtalk message basically pauses my music and starts it up again. I use the default music player currently. I did read that muting your phone is a work-around, but I'd rather not do that all the time.
3) Is there a way to play podcasts the way an iOS device does it, where it remembers the position you were even after changing tracks? Weird how I never even noticed that as a feature until I lost it!
4) This is a dumb question. I've installed titanium backup. Is it best to back EVERYTHING up on android, or just certain files/settings? Also, get an SD card for storage or can I backup directly to my PC (don't think a full backup will even fit on default SD)?
I'm playing with it a lot and discovering new things all the time, but the above is where I've hit a wall and just don't know anymore!
Love the phone (and OS!) otherwise.
