I also agree on the legal concerns of pursuing your idea on ClinicalFindings.com. My suggestion for this is for you to create a website about
clinical cases instead. The problem with this suggestion is that you have to do a very extensive research.
About
InterestingDownloads.com, my suggestion is a website that reviews the available freewares. Check
this website to see what I mean (trivia: this website ranks first in Google in "best freewares" query).
Math questions will also be good for
PracticeMaths.com, but I think it will also be good if you try doing a website about tricks on simplifying math problems without doing too much computation.
I still don't have suggestions for the other domain names, but for now i agree with DDC_cyn's suggestions.
