Joelcarlo makes sense. Different fancybox plugins use different versions of jQuery. PageLines is using one of those versions for the feature slider and other things. If you install a plugin that adds a different version, things are likely to break.
So, I'm going with Catrina's suggestion to try all of them. You can visit your site, view source code and you'll see which version of jQuery we're using and select a plugin using the same version. Those plugins should work and not affect other things, such as the sliders and carousel.
