Popping noise when pressing the gas pedal???

[B2r3y]

OK well today when i was driving around its more of a thumping sound hitting somewhere in the drive train i beilve, or thats where it sounds like its coming from. i usually like to do work on my car rather than take to a mechanic but got a old friend who know alot about cars he siad he would put it on a lift in the morn and see what it is. said it might be a transmission mount or something. see sometimes i hear it right by the shifter and back some and sometimes it sounds like its coming from somewhere near the back.

also has anyone noticed say when your going over 30mph and no radio on, have you noticed a constant squeeky sound coming from somewhere that sounds like its in your dash? if anyone has had this problem or knows what im talking about any help would be appreciated becuz its really annoying.
thanks
