When you're applying, do your homework. That is: any job offer you want to apply for you should read carefully and extract what exactly they want from you and what they offer to you in return. For your application you want to incorporate what they require, however it needs to fit to your own character (aka don't lie because they'll notice sooner or later, anyway). Try to avoid common phrases, you want to catch attention afterall and when the employer has to look through a ton of applications that all sound the same one that's different, but still correct, will catch their eye.
Check your application for spell errors etc. This is particularly imperative because if you don't then that already gives of a negative impression of you. When in doubt let someone else proof read it.
In terms of resume you should check out what is the current standard. I don't know the US, but I do know that there is one for European countries.
When you get to the interview part then do your research. Figure exactly out what they are doing and why you want to work for them, that is one of the questions they are going to ask you (and don't bring up money until the end of the conversation). When they ask you a question don't just answer with yes or no. Instead elaborate on your answer. Afterall, they want to know you better and what good of an expression are they going to get if you keep answering to a minimum?
Keep in mind that when a company talks about being social and communicative that's not a requirement. It's what they offer to _you_. They are trying to lure people in with that, not scare people away who are hard to communicate with. The logic is: if you're not willing to communicate then this job may not be for you.
The money talk: at some point during an interview, that is when it reaches its end, and if you're part of the workforce (so no trait school student, etc.) you want to talk money. Before that, however, you should do your research on how much someone in that industry actually earns otherwise you're just going to make a fool of yourself. You are allowed to negotiate, but obviously you won't get as much out of a smaller company than a big one.
