Obenauf's LP is a great product, and will keep your leather conditioned and weather-resistant. I use it on all my RWs, including my GTs.
I'm partial to the Superfeet insoles in my RW boots. Relatively inexpensive, do the job as far as comfort goes, and are long-wearing. I'm use the green Superfeet insoles.
