Congratulations on getting that camera. The 180 is really nice in that it lets you set the exposure manually. Most other models have electronic shutters with exposure automation. Operation is pretty simple and straight forward. The Land List Dead Link Removed provides lots of information on pretty much all polaroid cameras. There's a howto page for packfilm cameras at Dead Link Removed.
As for film, Fuji FP-100C, FP100B, and FP3000B will fit, as will the now discontinued Polaroid peel-apart films. The fuji films produce very nice looking images.
I hope this helps and happy shooting!
