Skyhigh,
I do not want to get too far afield of what you have asked for, but would like to give you a little something to think about:
Photoshop is build around Raster Images, i.e. Images composed of pixels. Most of the formats that you mention are pixel-based formats. While those can be Scaled, within reason, they do not offer the flexibility, that a Vector-based Image can. That is why most logo work is done in Vector-based formats, such as AI - total Scability - as has been mentioned.
For the use, that you describe (if I read it correctly), you might be better served to use Adobe Illustrator, which you already have, and adding Adobe InDesign. It is a page-design program, and can do such things, as business cards, with ease. It even comes with some popular Templates, where you would just add the elements, and Type, required, and would end up an 8.5 x 11 page of cards, that could be handed off to a commercial printer, or even run through a good desktop inkjet, or laser, using something like the Avery "clear-edge" business card stock.
InDesign will work wih Raster, or Vector art (what you already have, and have paid for), and handles Type much better, than does Photoshop.
I am not saying that one cannot create and then print business cards (only one application here) from Photoshop, but that it is likely not the ultimate tool for that purpose.
I also highly recommend Adobe TV, but you may have to spend some time finding the tutorials, that will help you.
Good luck, and just something to think about.
