Ok, so playing around with it some more, it I noticed a few things.
-If the person doesn't have any description written for their product, that seems to be what causes the text to overlap like this:

HOWever, I went and added some description to that product, and it didn't overlap suddenly:
http://i194.photobucket.com/albums/z137/h_griego/xex5.jpg
Also, it seems like it won't overlap until you get more than two rows of thumbnails below the image. Then the thumbs start running into the text.
SO I don't know if it is the text we need to 'lock in place' or the image actually. It seems like they are not 'connected', kwim? Like if you make the image larger, the text doesn't move to compensate, etc. Sorry, hope I'm making sense.
