As TorgHacker said it's GM's call, I'm not actually disagreeing with her, but I'd make a slightly different call on the second question (if you grappled, can you pull them down). I'd say no.
First off, unless you restrain them, at a good success or better on the grapple, there's no limitations on their movement anyway, so no reason to give you control of pulling them down. But then, if you do restrain them, you get to hold them in place, they're flat footed to all attacks, and the only action they can take on their turn is to attempt to break free. It does not give you control over their movement, and I wouldn't add that since it opens up a big can of worms. TK only lets you do things you can normally, just at a distance - that's the whole point of this errata, and I wouldn't add movement control to restraint as an exception - keeping in mind I also don't allow you to move someone you've restrained in a normal grapple.
That's a good point.
Can I mention how much I just want to take a bunch of dynamite and blow telekinesis up and do it over again?
