Personally, if I were trying to help a company sell their products, I wouldn't be overly concerned about it - unless you are somehow defaming their name in the process. This is a common practice to discern the various manufacturers, and if somewhere down the line a company doesn't like it, you would probably get a letter request to remove it rather than them spending a ton on litigation.
To expand on kodaks post, you might consider adding 'All other product names and company logos are the trademarks of the respective owners,' after your own copyright notice.
Over the years, I've found that some of the bigger firms are more concerned about maintaining minimum online pricing levels and territorial concerns - rather than whether or not their logo is used for a legitimate sales effort.

The US copyright and trademark laws revolve around the protection of commerce. The only way, I know of, to get into any real legal trouble is to somehow damage the owners’ ability to generate revenue or directly taking revenue that they would otherwise have received.
The law also states that an effort on their part is required to ensure the public is aware of possible infringement, meaning they have to contact you and tell you they don't want you to use their logo.
I am not a lawyer but have been involved in several significant trademark/patent cases and this is my experience.
