Both of your questions have the same answer. The game entities and the props are both in their own maps (VMFs), and you need to open them up in Hammer like you would any other map. By default they are installed to steamapps\common\Team Fortress 2\content\tf\mapsrc, which should be the default directory Hammer uses when you save/open maps... but it turns out it isn't anymore.
I just went to check by deleting my config and letting Steam remake one. Apparently the default directory is now steamapps\common\Team Fortress 2\sourcesdk_content\tf\mapsrc, which would explain why so many people have been having trouble finding the libraries. I'll have to get an update out and fix that path. Actually I think it is about time I bother writing my own installer so I have more power/flexibility at my disposal.
goddammit Valve why can't you just fucking bring back the working all-in-one SDK
I can't find your early post about it, but looking at my doors I wasn't experiencing this... you didn't by chance rotate the doors, did you?Oh, and on top of the stickies sticking to doors problem (incidentally, what's the fix for that again?).
I don't know if this is because I was using an old version, but some door prefabs have the dynamic prop part of the door set to solid, where its collision pokes out past the brush func_door, and stickies stick to the prop and stay in the air when the door opens.
