oh that's not so bad, we can use Gingerbreak, but you still need ADB
adb is not an app, its something you need on your computer..
the first thing to do is install the USB drivers for your device, more than likely when you first plug your device into the phone it will show up as a CD drive and have some drivers to install?
once you have done that, you need to follow this guide:
Once you have done that you should be able to connect to you device from your PC, and then we can root/dump it.
NOTE: there is a GingerBreak App, but we do not want to run that just yet since it will modify your device and we need a romdump before its modified.
