Visiting LDS Family Search Centers & keeping records

I was wondering if anyone has visited their local LDS family search center. What's different from what you find online at familysearch.org? Is it worthwhile to go? One's here in town, and I'm debating. Will they try to convert me? ;-p

Also, how do people organize their genealogy papers? Besides online, I like to keep physical copies, because it's easier to look and find stuff. Do people have a different binder per person/family/etc?

Just started doing this and not sure what would be best way. Currently have paternal and maternal binders, with dividers for direct descendents, followed by siblings, next generation, siblings, etc. I also have maps in the binder.

Thanks!
