As Todd said we need to know more in order to give any insight into why your MOVs are slowed down, but perhaps you haven't correctly interpreted the footage.
As for the audio, does it play when you do a RAM preview? Here are some things to check when previewing audio:
a.) Make sure the audio icon is switched on for the clip you're trying to preview.
b.) Open the audio waveforms to make sure your clip actually has audio. You can also check the audio levels to make sure they're loud enough.
c.) Make sure the audio is turned on in the RAM preview panel.
b.) Finally, you have to do a RAM Preview in order to hear audio in After Effects, so make sure you click the RAM Preview button.
If all these things are working correctly in with a RAM Preview then the audio should export from the Render Queue with audio enabled.
As Ben said, there's many more things to it than just saying that something isn't right. Provide more info and perhaps we can get you on track...
