My UI is a mix of LUI http://www.wow-lui.com and other addons. But mainly credit goes out to Loui. I been using LUI since it came out and I have never looked back. As much as I tried to see if there was something better out there, there never was.
Step 1 - BACKUP YOUR WTF / FONTS (if you have one) / INTERFACE folders. This is a mandatory step. I suggest creating a folder on the desktop named "Backup WoW" and placing it in there.
Step 2 - MOVE the WTF/INTERFACE/FONTS folder out of the WoW folder. We need the WoW folder to not have the 3 folders inside.
Step 3 - Copy the Contents of my Zip file into the WoW folder.
Step 4 - Fix the WTF folder to match your account info / server info / toon info. ALSO FOR ACCOUNT NAME USE THE NAME NOT THE EMAIL. For instance mine is Bertybert NOT consolecrusader@gmail.com
Step 5 - HIT INSTALL WHEN YOU LOG IN.
Bartender 4 - Use profile name Rikroll
Quartz - Use profile Towelliee - Kil'Jaeden
