The barrel cone seams like a great idea for the cost. The portable winch looks good. The rope gives great control when pulling. Make sure you get the correct rope, and good rope will be costly. It is a much better idea then an electric winch with a wire cable. I would forgo the tongs and go with this portable winch and barrel to get started. I would add a clevis to use in the tractor draw bar and 2- 1/4 inch Grade 70 chains. Lighter to drag in the woods yet very strong. One to tie through the barrel as a choker and if needed to tie the choker to the tractor.
Cycledude's post with the sled would be by next purchase if the barrel does not hold up. I bet you could find a welding shop that could make the sled a little cheaper.
Safety wise use the fixed drawbar on the tractor until you get a lot of experience as people are prone to overload the three point arms making the front end get to light.
