A300 flight crew experiences loss of captain's airspeed tape and autopilot at FL350. Autothrust advances to full power resulting in a momentary overspeed until control of the aircraft is passed to the first officer whose instruments are unaffected. Static makes communication with ATC difficult.

Narrative:
At FL350; in cruise; approaching weather that was ahead and all around but was avoidable by 20 miles with vectors; the captain (PF) lost airspeed and flight director information. The autothrottles advanced to near full power and other minor warnings were noted from the ECAM. Static on the radios made communication about our issues with center impossible and several calls on guard were finally received to get us back in contact. Additionally the altitude control of the autopilot would not maintain altitude and the altitude alerting system was malfunctioning. After swapping aircraft control to the first officer and captain switching to alternate flight director and airspeed; we flew to destination with the still malfunctioning autopilot intermittent and marginally audible radios.
