10 speed Q's SRAM/Shimano, current wheels

[TBLS]

Just picked up a cross bike with 10 speed Rival...first foray > 9 speeds. I searched and believe the answers to my Q's are 'yes' but appreciate advice/confirmation

>Can I use either a sram or Shimano 10 speed cassette?

>will a 10 speed cassette work with my current '9 speed' wheels (Easton Circuits, Ultegra 6500)

Thanks!!
