Good question... I'll give ya a little insight... But I also have a simular problem with my own truck.
Part of your problem is the ammount of contact the tires have with the ground, createing friction, much more than a stock size tire would have. When you start to move, the tire rolls, and allows the friction to be less, and then you can steer the wheel. It's easier to steer a tire in motion than one sitting still. Smaller tire = smaller contact area = less friction = less effort to steer. So, long story short, a lifted, big tired truck is gonna be alot tuffer to steer when sitting still than the same truck with stock tires.
However.... I also have a simular problem with my truck, and it's got stock tires. My guess is that the power steering pump isn't up to the job, and/or the steering gear box is not working properly. I hope someone with more knolage will chime in and enlighten us both on this issue...
As to the rubbing, what are the tires hitting? I think hitting the leaf springs is common, and aside from the annoyance, I don't think it will cause any real damage. I've run mud trucks like that for years, no harm. Just keeps the paint worn off in one spot!
Good luck with your new ride! Welcome to the brotherhood of diesel!
