I usually used to use www.dynamicdrive.com for my scripts. I don’t use them anymore because I learned how to do javascript myself. I do still check out DD just to see what other people are doing.
A no right click script is also available on DD, they even have one where no alert pops up, instead you just can’t right click in the window period. This doesn’t prevent anyone from stealing your content though. They can easily use CTRL+C to copy or go to View/Source and get it from there. But if you want to use it you can get it there.
I hope this answers all of your questions.
