I've heard from several different sources regarding the cross bars that Toyota may no longer be offering them as an accessory however they are still listed on the Toyota.com site as an accessory. May be something new for 2010 though. Personally I have them and love the fact that I can attach Thule trays to them with no modifications or adaptors. If you find some of my early threads though you'll find the frustration I had though with Toyota and Yakima as you can't get extra clips for adding accessories. It's been like that since the 05's as the clips Yakima says fit the cross bars don't. Also the fact that the bars are only rated for 50# each limits their ability to carry anything but a few bikes. If you find some plan to go with Thule bike trays as they fit very well. Forget Yakima as you'll have a PITA time trying to find anything that fits properly.
Here's a pic of my setup. I have added a third tray since this pic and carry three bikes now. If you plan to leave the front wheel on then plan to have them stick out over the rear of the bed if you have a short bed like my truck.
