I pulled out the window sticker for my '07 Wrangler and it stated that the 410 gear was included with the automatic transmission package which included:4 speed automatic transmission, transmission skid plate, and 410 axle ratio. I do not have the towing package so I don't know if it was included with that package or not. I did read that the standard axle ratio was 321 which I think is way too high for a Jeep especially if larger tires are added at some time. Higher gears would take all the torque away.
And yes to your second question. The extra stitching is reported to have lowered the wind noise on the soft tops.
With this Jeep, the days of soft tops are over, had them on the last two Jeeps. The new Jeep is real quiet with the Freedom Hard Top. When I want to go "topless", I ride my Harley.
