At work I use a wireless Logitech Mx700 mouse with a standard belkin usb keyboard. I do like the wireless although for gaming I prefer the Mx510 I have at home.
Logitech MX 518, which is a gaming mouse. Runs about $40 at NewEgg. I have a Wireless Multimedia Keyboard by Microsoft. Only spend extra money for a gaming mouse, any other keyboard/mouse combo will do for internet browsing.
