The gear Tech Guru & MrClass proposed is top notch , but let's be realistic , you probably cannot wait for shipping from outside leb and want some gear already available here .
So ,HyperX Cloud2 Headset , that MrClass and I proposed , should be available in most stores at around 80 $ .
For the mouse , try to stay away from MOBA mouses because you also play FPSs , the extra buttons may be annoying . Here are the best mouses you can find in lebanon :
You've got the Razer mices ( deathadder , ouroboros ) available in most stores with prices averaging 70 to 100 $ , I personally do not like razer as alot of their products suffer from flimsy build quality .
Go for steelseries or zowie mouses if you can , those are top notch but are only available in 2 places in lebanon ( as far as i know ) which are the net caffes Ground Zero and Spotnet , both close to Hamra .
For the keyboard , if you can get your hands on a K70 ( same as TechGuru's for less than 170 $ , then get it ASAP . The K70 is very popular and barely available in most stores in lebanon . 2nd choice are Razer mechanical keyboards if you can't find any K70 , price should be around 90 to 150 $ on pcandparts
Pcandparts has added a whole lot of Roccat products on their website weeks ago , you may want to check them out also .

I actually have the Zowie Ec2-a , a decent A4-tech keyboard ( never liked mechanical ) and a HyperX Cloud 2
Good luck with your choice
