1)As I load my source in MovieStacker, under "streams and authoring" it shows that the fps is 29.97. I then follow instructions and go to TMPGEnc. I open the avs, and load the target template. Now, under "video" in settings, the frame rate is 23.976, do I change that to 29.97 because my source was?

And that's the trap of some DVD sources.
Its shown as 29,97 but really its not interlaced or telecined .. its still at 23,97 with a pulldownFlag set.

Here I explained how to reencode a progressive DVD source with TMPEGEnc and why we don't do a "inverseTelecine" or even a conversion to real 29,97
Most of the Hollywood movieproductions which are based on film are progressive and "real" encoded at 23,97 FPS!
To author a DVD they add a PulldownFlag so the 23,97 FPS stream is shown on the PC as a 29,97FPS. By playing this PulldownFlagged Stream in a stand-alone-DVD-player the player recognizes the PulldownFlag-information and does an internal pulldown, so the 23,97FPS stream will be pulldowned internal to be viewable on your Tv as an interlaced 29,97 FPS analog NTSC VIDEO Signal. Cause TVs cannot handle progressive NTSC FILM signals.
And that's also shown as standard at DVDrHelp.com:

Shure a pulldownflag information can only be added to a MPEG2 Stream and we know that MPEG1 gives us better compression.
But a 23,97 pulldownflagged MPEG2 stream will give you defenitely a better CQ Value than a 29,97 MPEG1 (its explained in the Link above).
I'm still woking on a transaltion of my guide in english. When it will be ready, I'll post the link including the complete progress.
