Spiffy McBang
First time out of the vault

So I've worked over this quest, finally broke down and read a walkthrough, and discovered the two ways to beat it. But neither is working.
-Sherry keeps going into the same conversation. I suggest she takes up hobbies, and it ends on the one after that, either with me agreeing or with her getting annoyed. I can't get it past this part. Presumably this is a speech skill thing, so I'm not that concerned.
-I swiped the urn for Vinnie, took it to him, then said I had to do something before going after Neal. I went directly to Lars, but my only option was to "just say hello". I've also tried giving Neal the urn back first and destroying the hospital basement first. Lars just isn't giving the option to protect Neal. This shouldn't require stat checks, should it? He gave me the quest, he's expecting something from me, and in any case the relevant base stats are all 6, which shouldn't screw anything up.
I'm running version 1.2, so I don't think I need a patch. Any ideas for what I need to do?
