Seriously though, since you have no clue what you are doing with it, pay someone to config it for you. Otherwise, you need to spend some serious time learning how to configure your firewall. Asking these types of questions really isn't going to get you far with what really needs to be done to manage your ASA.
Based upon those questions, I would have to agree with Secter and tell you to outsource your configuration. You will have very little hope of properly configuring an ASA firewall without even basic knowledge of how to configure routers, and other equipment.
The ASA isn't the same as the Netgear router you run at home, its quite a bit more complicated and intricate.
