This might help and get you a wide range of selections. Click on 'search' on the main page of this site and type in what you are looking for in the subject box...a whole bunch of threads with links and all will come up as a rule for each subject/character.
Then you can 'go to town' looking at what ever topics/characters you prefer.
Also if you skim through the pages of this site at the subject lines, you are bound to see some of the same subjects you mentioned.
Hope this helps.
