Well I think you'd be a fan of the Logitech gaming keyboards (G11, G15 and G19).
The G11 goes for nearly €80, the G15 for nearly €85 and the G19 for €130.
Perhaps you can find yourself a cheaper deal for the G11/G15 in Spain, else you might have to consider purchasing on second-handed
Can't really advise you any gaming mouses as I have never used one myself (not a fan of them either).
I'd just read some reviews on them
