Hey man I understand the curiosity but there're already plenty of threads open about this game, with tons of helpful people around to answer any other question you might have.
For levity's sake, the controls are same as you mentioned above. In addition, holding 1 + shake will grab/interact with objects or other players. Jumping and pressing the down arrow will stomp, holding 2 after a jump will cause a mid-air boost when riding Yoshi. Additional commands are also available depending on which power-up is active.
