Sorry this is so late, but hopefully it will help.
For the guages you have 2 options, you can create 16 seperate images and make your own guage... or you can copy them from someone elses sensorpanel file. (just rememeber to say thanks in thier post or credit them in yours).
To use someone elses files, load thier sensor panel and then go to C:\Program Files (x86)\FinalWire\AIDA64 Extreme\SensorPanel whwere you will find all the files used to make the panel
Once you have the files, select Custome and then in the "States" section load them
