5w30 full synthetic is the most commonly used oil in that car. I'm not sure about your town, but around here the oil is actually cheaper at the dealer than anywhere else.
Check your manual to see if there is an oil weight better suited to your climate.
The oil change procedure is just like any other car, only easier - beacuause of the remote oil filter. You just need a 36mm socket ( I believe ) to remove the oil canister cap.
You may want to invest in a service light resetting tool for when you do your oil changes - theres also a way to reset the lights manually, but every time I mention it on this forum someone gets jumpy / iffy about it. I've been using it for years and it's never hurt anything.
Good luck and enjoy the new car
