berkley has a video on youtube on how to rig them up, check that out for an easy visual.
There are alot of styles really. I like to trim them down and use them on jig heads. pretty much I rig them like I fish rubber worms for bass, except that I use a sliding float.
my #1 piece of advice on rubber worms is to not get stuck using only pink. orange, red, green, brown, and black have all caught fish for me too.
