You can sell your stuff. Or you can kill people to get it. :)
In my opinion Fallout New Vegas is. In Fallout NV it is easier to make caps so you can buy better wepons and ammo. In Fallout 3 It's hard to make a lot of caps in the begining making it a slow start. But is you want to test your skills play Fallout 3.
Sorry, but there aren't any "cheats" in Fallout 3. There are, however mods for the PC version but that is all. Also, there are glitches to get more caps and such that can be counted as cheats if you want.
bottle caps
No, but you can sell them for caps, and it has no weight; so you can hold as many as you want.
Take them to the Regulator HQ and they will give you a regulator duster and some caps for every finger you bring them.
She is a hooker but does nothing but sleep does not provide any bonuses or active effects not worth the caps.
its pretty easy just keep killing raiders, scavengers, raid places, and loot everything.
You Can't Sneak In, You Have To Capture Some Slaves For Grouse The Gate Guard Or Pay Him Some Caps.

You can kill people and steal their stuff, and sell them. :)
You need 50 Sarsaparilla Star Caps to proceed to the next part of the quest.
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
