I need help with cleaning up after a major Trojan attack!

OS: XP Pro, SP3
HW: Toshiba Satelite A55, 1GB memory (maxed).

History: Latest run of Malwarebytes cleaned up 16 instances of Trojans.

Current Symptoms: Computer is sluggish to respond. Left clicking on a desktop icon to select it can take 10 seconds to respond. Right clicking can take twice as long. Systemidle process running 99%. I ran RootRepeal and obtained the following results:
