The following you around thing may or may not be special, it's hard to tell if she's guessing or remembering how you got out, if she actually saw you leave, or if she's 'smelling you out'. I kind of doubt she's sniffing you out, though. A game I've been playing with Frag since he was 12 weeks was to put him in a down stay, let him sniff a piece of cheese, then I walk away and put it on the floor. I say find it and he's allowed to get up and go 'find it'. Obviously starting out I did this a few feet in front of him, around a corner, but in plain sight, etc. We're to the point now where I can have him on the other side of the house, I drop the cheese a few times along the way (and pick it back up, just to keep the scent down) and place the cheese in a room underneath something or behind something. He goes straight for it every time without hesitation.
As far as her staring down strangers, that may be working against you. This isn't a protective instinct or having strong nerves at 4 months, it's her fear instinct. She doesn't want strangers coming near because she's afraid of them. I'd get her out there around hundreds of people giving her pets and treats to socialize her some more.
Just about any intelligent dog would be a good agility prospect, and most GSD are good schutzhund prospects. You won't know if it will actually work out until you join a club and get her assessed by professionals. She may not like agility, but I'm sure she'd excell at it if she did.
