If you are doing serious gaming I wouldn't get that I-Rocks stuff, just looks like a generic mouse and keyboard to me. That being said, I can't recommend you a keyboard because A) I don't have a wireless one and, B) Even though I have a Razer Lycosa (wired) and it's awesome I don't think it has improved my game in anyway shape or form, but it's still a great keyboard if you don't mind wired
Now, mouse on the other hand. I highly recommend the SideWinder X8 from Microsoft. That has improved my game and it is a bloody awesome mouse. So comfortable, my hand just molds right around it, note that it is a tad on the big side. I love how the thumb buttons are aligned vertically rather than horizontally, it makes them a lot easier to press. Another huge plus is the wireless receiver or "puck" It sits on your desk or whatever and has a charging cable tucked into it, so if the mouse is dying, you just snap on the magnetic cable and it begins charging. It's awesome.
The only downside to this mouse I can think of is that the feet (oh and it comes with 3 sets of feet to play with

) aren't teflon, they're just plastic so while it glides really nice, it's just not
as nice as some of the Razer mice I have had a play with.
Look how sexy that is
