Hi Al
Yes it can be very over whelming at first but believe me you'll look back at this one day and laugh about it.
An interface example would be the Focusrite saffire pro24, or the presonus audiobox usb, these are just a few examples but will get you a thinking in the right direction.
That AKG (normal as you put it) will work out fine for you.
Just NEVER go to a store and ask a clerk what you should get !!!!
For the most part they are clueless and if they're not the will sell you stuff that you don't need, just to make a commission.
It's best to do your homework as your doing now then walk in to a store (or purchase on line) with knowledge. Then if a salesperson is trying to take you for a ride you can tell them to go to the bathroom in their hat

Do you live in Milano Texas USA or Milano Italy? My guess is Italy and if I'm right You can look up a fellow member here on Home Recording by the name of fala. Just go under member list find him click on him then you can send him a Personal message. He lives in Italy and seems to be of great knowledge with recording.
