[Sigvaldi Loftsson]"What is the best way to get the DVD into FCP and back to DVD with little or no quality loss?"
Your video already suffered the quality loss when it was encoded to MPEG 2 for the DVD. So, ripping the DVD and re-editing the file is never going to be perfect no matter what you do. That being said, the proper way to do what you want is to use MPEG Streamclip (it's free) to "Export" the DVD to Quicktime, and choose the option for DVCPro. DVCPro is the leanest of all the codecs that works in 4:2:2 color space, which means it won't further erode any text and graphics on the video, which would happen if you chose to re-edit ordinary DV.
Deinterlace only if the majority of users will watch on computers. Furthermore, you should know that ALL DVD video is interlaced, even video produced at 30p or 24p. If the footage is progressive scan to start with, it isn't necessary. Deinterlacing tends to soften interlaced footage; you take a chance with degrading the image even more. Proceed with caution.
There is no law that says you can't burn a deinterlaced 2-minute segment to DVD as a test, then view the result on a variety of players.

Everything looks great now except for one little problem....
The thing is my client wants a small logo (watermark) in the top right corner of the video.
I got a .psd file with the logo, fixed it a little in photoshop and exported as .png.
I imported it into FCP and.....It looks bad.
Now my video settings are DVCpro50 NTSC with lower field dominance.
I know the graphics can only look so good on a DVD but how can I make them as good as possible?
