Welcome to the site
First of all, it's Blu-ray
Well the first problem is that TV is not 1080p so it will not accept that resolution. I believe the PS3 has an auto option. But you really should set it to 1080i. And make sure your 24fps setting is off!
What movies did you look at? Keep in mind black bars and film grain are normal. The grain has always been in the original film. Blu-ray simply enhances detail so now the grain is noticable. You are less likely to see film grain in animation, movies shot with HD digital cameras or movies that had some sort of filtering process done in studio.
