Ok everyone hold on to your boot straps, mainly newbies like me, cause I figured it out. Simple explanation. If you want a certain ringtone from phonezoo or places like it, send it to your text as either a SMS or MMS. Once it is downloaded into your droid (in my case it is the Droid Incredible) it will be saved to your music files. If you want that tone you downloaded to play as a ringtone, go into your music player and select the ringtone. Then hit "menu" and save as ring tone ( either call, contact, or you can trim the ringtone) and voi la.. ring tone.
If you want a certain sounds to play as an alert notification (this is where it gets only slightly tricky), connect your droid to your computer and set the connection type to disk drive. Send your sound file from the site to your computer instead of your phone via text. I use a Macintosh so I have an icon that pops up that says "Drive X" (PC's and other mac users I am not sure what yours will look like). Open that file or drive, and several folders/files will appear. Click on media/ audio/ notifications. Here you should see a sound file for facebookpop.m4a. Here is where you will put those notification sound files. Move files in with the other file.
Mac users eject the drive/file and set the connection for the phone back to "Charge Only" or one of the other settings. This should let the phone continue to use the SD card once again. In order to check I went to both the ringtone section and the notification section and looked at each list. Sure enough both contained the files i just added and they both played.
I have been researching this for the last 3 hours, now I know that sounds like a long time for a person to look, but I couldn't find any clear answers on how to do it.
