Do you have the TV's model number? Perhaps we can look up the users manual online.
When connecting analog cables, there are three connections. One is the video signal, usually with a yellow connector. The other two are audio left (red I believe) and audio right (white, unless I have these two backwards). You can't hurt anything plugging them in wrong, as the worst that would happen is left sounds coming out of the right speaker.
I honestly don't think you can hurt anything plugging them in and seeing what happens. Start with the yellow video cable, make sure the TV input is set to the jacks you are using, and then just plug it in to each jack until you get a picture. Of course, the Roku/BD player must be turned on so it's sending out a signal. Once you get video on the screen, you know the other two are your audio inputs. Just plug them both in and play something that might have some obvious left/right sounds. If they are coming out the wrong speakers, just switch the red and white connectors.
