Rubbing compound is probably a lot more aggressive than what you need. You want to remove as little clear coat as possible to make the swirls disappear. I don't think our clear coat is thick enough to wet sand safely, but you'd need a thickness gage to be certain.
Here's a good place to start: We Are Car Care -- Car Wax, Car Polish, Auto Detailing Supplies, Car Buffers & Car Accessories Store
They have a good selection of products and a lot of tutorials and information.
If you're looking for minor to moderate swirl removal, I'd recommend getting two polishes. One moderately abrasive polish (I used Menzerna Intensive Polish on the badly scratched areas. Then, you'll want a less abrasive finishing polish to remove minor swirls from the rest of the car without remove too much clearcoat. I used Menzerna Final Polish on mine. You'll also want different pads, as some pads are more abrasive than others.
If you've never polished before, I'd recommend a random orbital buffer (like the Porter Cable 7424) over a rotary. It's much less likely to cause permanent damage to your finish.
