Hi Michelle there have been many posts here about mics and recording gear. Most of these questions are posted on the two forums "studio and recording gear" and "microphone and vocalist."
I am sure you will come up with answers if you look back.

It would help if you tell us what you have already and exactly what you want to record....whether it is acoustic and vocals or electric and vocals and how many instruments and chanels you will need. It may be of benefit to buy a pickup for your acoustic guitar. It may be better just to put a mic in front of it. You will need a pre amp or mixer and probably some form of interface. It is always better to buy everything together to match rather than piecemeal. I do not think your budget is of any concern you will get all you need for that kind of money but you need to buy the correct stuff to do the job. I would suggest the bulk goes on a good mic.
