Naw man, your good. Newbies section might be a great place to start though. There are threads at the top of the forum, that will answer most of your questions.
If you are not looking for ease of use, and not so much 'quality', then a USB mic may be what you want. Problem comes when you realize you do want quality, and you wasted $100 on a USB mic that does no good in the future, after you go the better route of purchasing an audio interface, and a microphone that can be used with anything later.
In a nutshell, a recording program typically allows you to use only one input driver (interface or USB mic/which is in itself an interface). If you go with a self contained USB mic input, you cannot change your mind and use other mics at the same time. And you are typically dealing with low quality to begin with. Well, there are exceptions, but not cheap.
You are better off purchasing a audio interface and then you have the opportunity to try different mics. Trust me, no one mic is good for everyone. You are looking at maybe $200 for a low level interface and
a Shure SM57. That would be a good start IMO.
Read the sticky's man. Educate yourself, before spending any cash.
