Can anyone help with my problem? I'm dying to play right now but my game has been really buggy like this.
Uh, the 'clear all' as admin option should take care of the emitters.
The one in the second photo, under spawnmenu.utilities_tab, the second column, first choice. That should work, but I haven't had this problem. The hl2 weapons are easily fixed with sv_cheats 1, and then impulse 101.
I've never had a problem with the props, try verifying the integrity of the game through properties in the library.
