At the risk of sounding rude, which I do not mean to be. Let me ask a simple question. Can one really hope to write decent fan-fiction in M-E without having read darn near everything about it?
- Learn your elvish [or at least be able to make a darn good stab at names] if you plan on creating any. [ see HoME 5 and the index/appendices of UT and Silm]
- have a real good sense of the tale[s] of Years.[RotK and PoME]
- learn everything you can about all of the Maia and High-Elves [ if you are planning on the white council that is]. [Valaquenta in the Silm and UT chapter on the Istari as mentioned] also there is a stunning article on the limitations and not of the Maiar who are closed in the flesh by Jallanite, which again might help immensely w/ background realism see

- learn what you can about the first white council, that preceded the WC of the third age.[Of the Rings of power and the third Age, Glorfindel essay in PoME as a possible member of the Council
- Have a good sense of what the politics of Gondor and Arnor were, in case you want to mention why they did or did not invite the Steward and the Chieftan.
- I could go on, but my point is, is that Middle-Earth is so amazing because all of the strands of history are so interconnected. So in order to attempt to weave another strand you must be intimate w/ all of the surrounding material.
I can tell you what I have done was to take mental notes re: all of the aspects that really touched upon the area I am trying to write on [ elvish singing and thought-sending in my case], and as I make my way through the 20 or so books that touch upon it, I collect the essential quotes.
Good Luck!
If you feel I have been a bit unkind and or hard, feel free to post a scathing review of the begining of my first fan-fic at my Osanwe link below. [ see the weekly articles forum and then the Tale of Linuial post 2]
