Been playing for a while, career only pretty much. As a spin bowling allrounder
I actually find it easier to bowl spin as you can't bowl a no-ball... if the meter things time out then its just a shitty ball. I have gotten it down pretty well and take a decent amount of wickets by varying the deliveries etc. You have to know the type of delivery and then when you going to bowl it push the stick in the direction you want it to go to get your line right... (i.e. bowling off breaks outside off makes sense so dont bowl in on leg stump etc.)
Batting is a little bit harder to me especially in career on pro because you have to use the left stick for footwork and the right stick for shot type/timing.... very satisfying when you get it right though. Took me a while but I made my first ton this weekend.
I always drop catches off my own bowling though, I know you have to do something with the right stick but what exactly?
Also head over to the planetcricket forums if you want to download some cosmetic mods (bats/kits etc.) Some really good looking stuff over there.
