Okay we get it you're a noob and after a few months in OFPEC you won't be.
1.) In the civvi's init line put:
this addmagazine "M16";this addmagazine "M16; this addweapon "M16"
Put more addmagazines for more clips. This gives you a M16 with two clips, one is already loaded into the gun.
If you put addweapon first the AI has to reload first.
2.)Dunno really, look for something on texturing units...
EDIT: I type too slow.... :'(
