Inspiration
There was a thread a few weeks ago on reading lists for the Feywild inspiration. I added many of them to my To-Buy list, and others I recall. They are:
Changeling: The Lost (White Wolf)
Lords and Ladies by Terry Pratchett
Jonathan Strange & Mr Norrell by Susanna Clarke
Blood and Iron by Elizabeth Bear
The Stolen Child by Keith Donohue
Summer Knight by Jim Butcher (my personal recommendation)
Sandman (Vertigo Comics) and Neverwhere (novel) by Neil Gaiman
Faerie Tale by Ramon Fiest
The Broken Sword by Poul Anderson
War of the Flowers by Tad Williams
Hellboy II and Pan's Labyrinth (movies)
With that said, a general tip is that fey are alien mindsets, and they operate under different rules or laws. Such as: If you take food or drink they offer, you might be under their power, or you might owe them something significant. A promise made by a fey is always kept. Faeries cannot tell a lie, but they never tell the truth.
Organization
Buy you a three ring binder. In the binder, you should have a folder, notebook paper, and some cheat sheets. Have a bunch of names (mainly NPCs, but also sites and items, tales and songs) to reference when your mind goes blank.
Buy yourself some 4x6 inch and 3x5 inch notecards. The 4x6 inch ones work great for monster statblocks. 3x5 are great for magical items, power cards, quest cards, and notes to pass to players. I carry my monster cards and magic items in separate sandwich baggies.
Write out treasure parcels and magical items ahead of time, on a piece of notebook paper. Then, when the opportunity comes to give the PCs treasure, just reference your treasure sheet, pick one, and mark it off your list. I do this at every level, so I don't need to grope around.
Misc items at the table
I use post-it notes for conditions. Just jot down the condition, slap it on the player's shirt. But then, I'm cheap.
Multi-colored pipe cleaners work for marks (if you have multiple marking types; if you have one, the paladin or fighter likely will remember).
FrankTheDM has a great way of making cheap minis. Go to
this thread, where Frank makes available tons of sprites. You download the sprites, then put them on a piece of paper, print it out, glue the paper to some card stock (I use empty cereal boxes), cut out. Instant mini. I also use colorful aquarium rocks for minis.
Misc
I know that you write many a gaming project, so you may not need this. Even so, it never hurts. Here's a bunch of monsters:
The_Jester's conversions; the Redcap and Shimmerling Swarm might be of most interest.
Keterys' original monsters
Monster Compendium over at the WotC boards.
I have attached a sheet with just Conditions on them. I highly recommend you print and put that in your folder for quick reference.
