Lookup JayBird's false bottoms from http://norcalbrewingsolutions.com/ They're a bit pricey, but they work great. Otherwise, Sabco makes a good false bottom.
As for pumps, I use an older Chugger pump and I like it. They've got a new model coming out, but are currently out of stock on their website. If you're needing one right away, can't go wrong with the March 809.
