Oooooh, lemme see if I can cover all this in one go...okay!
1) Lockpicking (lock-sonicing?) is fine. Don't expect them to be super happy with it, and I would like a heads-up first, but yeah.
2) You already know Pollo knows the Eighth Doctor, I believe. They were rather good friends, as far as that goes. His fourth-wally memories were lost when he was reprogrammed, so he only knows what he's observed or been told, which is pretty much that the Doctor's from Gallifrey and he's awesome. xD He doesn't even know about regeneration, so he probably won't even exactly recognize that they're the same person at first.
3) Harvey here is from the other side of the fourth wall, too. He lives with a bunch of nerds, so he's aware of Doctor Who, but he's not a huge fan himself. I'd say he's probably seen bits and pieces of nuWho, but doesn't really follow it. He's really more circumspect than to tell people they're fictional where he comes from, so at most he might just make mention of basic things like knowing he's a time-traveler who saves people or whatever. Probably only if it comes up, though.
4) I ALMOST FORGOT. Pinkie Pie very briefly met the Second Doctor at iJAG. Being Pinkie Pie, she still remembers him and considers him a friend, but he wasn't around long enough for her to know all that much about him.
