I recently bought a PowerSwitch Tail II but later found out it their is a loud click. (I think it's a mechanical relay) .
Do mechanical relay give a loud click?
Is their a quieter version? (maybe a solid state relay). And when connecting a relay to a micro controller how do I protect it?

Yes, these use a mechanical relay. There is a solid-state version of this (for non-inductive loads). But we do not carry it in the store. It is available direct from the manufacturer: http://www.powerswitchtail.com/Pages/PowerSSRTail.aspx

Re: PowerSwitch Tail II
And to answer your other question, from the product description itself:
New! The Power Switch Tail II now is opto-isolated so you don't need a transistor or protection diode. The input acts like an LED so its safe for use with any microcontroller or logic pin.
