Getting used to a new work flow always comes with some problems. Perseverance is key, there will be some things that you will like more about Avid, and there will be things you like more about Vegas. It's always good to know the tools...
1) At the bottom of your timeline in the very lower left hand corner of the window, is a "hamburger menu" (it used to look like a hamburger back in the day, now it looks like a rectangle with a black line in the middle). Click on that, and a drop down menu will open. Select Audio Data and then select "sample plot". You can also view by energy level (volume) or both at the same time,. experiment with the settings and see what works best for you.
2) I'll need more info for this one. What are the different types of video you're putting into the project. What are your project settings?
3) The Avid codecs should be installed on your machine. You can use quicktime pro (or any other quicktime app) to export Avid video.
4) make sure that both your audio tracks are selected (a1 and a2 buttons on the right column of buttons) they should then be locked together for any editing and effects you apply.
5) No. You have to use the audio mixer. I agree that Vegas has better audio capabilities. However Avid is not really designed to finish audio, it's purely an editing tool. They expect at this level that you would export the audio for a final mix in a dedicated audio editing program (there are several export options for audio). You have to use the effect tool to adjust opacity.
Don't get disheartened there's an initial frustration in trying out any new software. Keep plugging away and once the "penny drops" about the workflow, you will find out why the top end editors still use it.
