Starcraft performance questions

i am a near gosu starcraft player that has played since 2000 and ive managed to take down a lot of enemies on non money maps and stuff but i have a bad keyboard/mouse combo theyre both stock peripherals that came with my dell dimension 8250 and stuff. I recently built a geforce 9600 computer from extremetech.com. And i feel even worse about my keyboard/mouse because i think they're hindering my performance. Do any of you guys have recommendations on a keyboard/mouse combo that i could buy i would be very grateful

oh ok thanks btw thanks for not bagging on me because i claim to be near gosu i went on several other forums and all they did was make insults at me.

btw do you think that a ati radeon hd 3650 would be good enough to play starcraft II when it comes out? because my friend is worried about being unable to play it cause he bought a cpu from shopl2.com for cheappcgamer_revival

I don't know the requirements for Starcraft 2. But assuming they are on the low side he will be able to run the game on the lower settings. If he wanted to run the game on medium-high, he should pick up a 9600GT.
