You will be happy you got the 6" or 7" which is what I use. Makes the job go a lot faster. The wool disk being the your best choose if using the 3M products.
The problem with using a drill is it is very easy to go right through the thin layer of gelcoat on the trailer as you can't controller the speed as you can with an actual variable speed power buffer.
If looking at the different types and if your not comfortable using one of the high speed polishers the pros use which if used incorrectly can also damage the finish your best to look for a variable speed "orbital" polisher - its much harder to do damage to the finish with one of those. I have found the ones that have the handle off to the side such as the Porter cable pictured below to be much easier to use & control then the ones that have the handle right on top over the disk area.
I am fortunate to have a "Car Guy" next door who also happens to work at an auto body shop. So he came over and showed me how to correctly use the high speed polisher he had when I first got the trailer and needed something with a bit more power to take off the 16 years of heavy oxidization from the top of the trailer. Since then I have purchased my own variable speed "orbital" polisher that helps make the yearly wax job go much faster.
There is a pretty simple write up giving the pros and cons as to the various types of buffers found here
