If you like the film look then you will want to go with 23.98 fps (24). Film is Progressive.
A Project Properties preset you might like is: XDCAM HD422 1080p24
It is 23.98 and 1920 x 1080
i stands for Interlaced. That is because if you shoot 30 interlaced frames per second then you get 60 fields.
Hope this helps and best of luck.
