Keyboard and mouse advice

Just built my first pc, loving it but currently using an old ps2 keyboard and a generic hp mouse i had lying around. 


I was wondering if i could have some advice on what kind of keyboard and mouse i should look for. 

I want something backlit if possible, nice and small to fit my desk. As for a mouse something good that's either left handed or ambidextrous. I don't really like having tons of buttons all over the thing, as long as it's comfortable and works well I'm happy. 


Thanks so much in advance, i really don't know what i should be looking for here. 


Oh, some media control would also be nice if at all possible.
