Ok, don't take my advice as having any sort of weight at all.... but fan use/reviews/parody can all be viewed as fair use (for proof of this look at pretty much any pornographic remake, such as 'Not the Munsters' or 'Not Married with Children', these are both clear contravention of intellectual property, further more they bring the trade maker holder into disrepute, but because they have a parody sticker on the front they're able to be sold).
So long as you aren't directly making money from their trademark (somewhat difficult to do...), and you have clear disclaimer pointing out that your site is only for information/fan/parody purposes or something similar then it can be termed fair use (a text book example of this wuld be the Wikipedia entry on say, coco-cola, uses their brand, logo etc and has all the legalise to explain why its fair use).
Now the thing is, none of this will help you if they decide to come after you (the entire system is totally skewed toward big business), but what you can do is make yourself a lower priority target. For instance in my niche there are websites with the EXACT trademark offering downloads for all their products, I however stick to information and revenue that doesn't mention them at all. The fact that they haven't defended their IP against these worse violaters should mean that they have given up their right to it (IP law states you have to continue to defend your IP if you wish to keep it), obviously no judge is going to rule against a big company, but I should at least have some warning before they come after me lol
(Like I say though, I am not in anyway legally minded, and most of this is probably bullshit)
