I did a quick search and found a few of these, but not many were complete and most were walls of text, so here is an attempt at a first contribution.
Neutral AH Guide
1.)Things to know:
a.)Majority of the time, people only visit the neutral AH to buy items only available to the other faction, therefore you should only sell those items.
b.)It’s usually recommended that you post items for 12h durations, since people will tend to undercut you within the first 1-3h (depending on the server/item), but few people tend to post on the neutral AH, so it’s suggested that you do 24-48h durations. The deposit on the items you will be selling tend to be very low anyways.
c.)Most of the items you will be selling will be readily available to you and the other faction will know this, don’t be a dick and put a rabbit up for 500g. You’re only hurting yourself. (I see people do this all the time.)
d.)Don’t flood the AH, again, common sense. On the higher costing recipies, post only 1-2, people tend to not buy your items if they see you have 10 white recipies up for 150g each. They will automatically loathe you.

ix.**** Savory Delight**** Now, this item. Alliance are able to obtain this as well, as its dropped by any mob in the barrens, but seeing how no ally levels there, its quite rare on ally side. Its possible to make a profit by buying it off horde AH, and jacking it up on the neutral.
Q/A:
How Can I make this easier? --- Download Auctioneer if you don’t have it first of all. Secondly, have a bank alt with 16 slotters bags equipped on him and all bank slots just for the neutral AH that you park in BB or Gadget. And lastly, I do this on a mage that can port around, making the gathering much MUCH easier. Also for horde, parking an alt near the black tabby mob spawn area, and check it often.
WILL I MAEKS WOW MILLIONS!? --- No, but you can make a significant chunk of gold on the neutral AH. This is not my main method of making gold, but brings in a nice additional income to the ever popular JC/DE technique.
How should I price? --- I set the price for ‘normal pets’, i.e. cats, around 9-15g, and they sell well enough. Recipies should be about the same for certain ones, some go for upwards for 200g, such as kaledori and moongraze. It depends on your server economy really.
How much do you make from this? --- Average is about 1.3-1.9kg a week so far, for about 1 hour of running around. (I don’t grab EVERY single item in this guide, also I’m alliance.)
1.9kg IS NOTHING, DO DAILIES --- Diaf?
Any other tips? --- Lifelike Mechanical Toad is an engineer created pet that is hard to find on some servers, on mine people sell them for 90g ally side, but horde side they go around 250g. Exploit that and make a profit.
