Hi Andy Garcia and welcome to the forums!
Rooting does not change the phone at all: it simply gives you access to the phone's forbidden system files. What you DO with that power, however, can have a tremendous effect on the phone.
If you're referring to the original Motorola Droid, it is relatively easy to root.
The desserts you keep hearing about are the versions of the Android Operating system, which are named after sweets. For example: Android 2.2 was Frozen Yogurt (or Froyo), 2.3 was Gingerbread, 3.0 was Honeycomb, 4.0 Ice Cream Sandwich, and the new 4.1/4.2 is Jelly Bean. Each one has advances and advantages over the previous one... but not every device has the capability to run the newer versions.
You might want to hang out in the Droid forum for your device, in the "All Things Root" section. There you will find all the answers to your questions. Most of all: ask yourself WHY you want or need to root, and then start there. Read, read, read, and ask questions
before doing anything!
Hope this helps and it's great to have you aboard!
