Most professional ethics codes include rules designed to avoid the "appearance of impropriety," and I think that this is a good rule of thumb to use for these sorts of questions, as well.
I'm a DM, an Adventure Path Subscriber, and also a player in other people's games. Currently, I'm playing in a Carrion Crown game. When the game started, I had read a good chunk of the first book, and I'd flipped through bestiary material of some of the other books, looking to mine them for ideas for my own homebrew game.
When I joined the Carrion Crown game, I did the following:
1. Full disclosure: I made sure that the GM knew that I had a bit of inside information on the early books, to ensure he was comfortable with it.
2. Avoidance of anything that might look like "insider trading:" In Book 1, there's a particular encounter which turns out to be an ambush, in which the PCs are manipulated to make themselves more vulnerable to the attack. I knew it was coming, and what's more, I knew that my PC was likely going to be the first target. My character is a pretty cautious fellow by nature, and it's likely that that he would have taken precautions during the run up to the attack, but because I didn't want to give the impression of metagaming, I kept my mouth shut and intentionally did NOT put up pre-emptive defenses. My PC nearly died, but no one could have accused me trying to game the system.
3. Cease the potentially abusive practice: I haven't cracked the spine on any of the Carrion Crown books since we started playing. At this point, we're somewhere in book 3, and I've got no idea what to expect.
For me, this was a no-brainer. Part of the thrill of the game for me is the thrill of exploration and discovery, so reading ahead would ruin that aspect of the game. Even when I play video games, I generally play through them once while avoiding any kind of spoilers or walkthroughs, and then use walkthroughs as a way of checking out content that I might have missed the first time out.
I would expect players in my game to observe a similar social contract.
