Barbell Info
I purchased one barbell from <<<GASP>>>> the Firm! Great Evil Workouts that people here love to make fun of like lemmings! Not all, make fun, mind you, just the lemmings.
It is padded and my favorite.
I also purchased a barbell from GNC -- which I use for upper body work.
That way I can keep two barbells loaded -one for lower body (padded Firm) and one for upper body (which I load at about 25 pounds).
I have such an assortment of plates, I can't answer your second question except to say that for Lower Body I load the barbell at 45 to 55 pounds and the Upper body at 15 to 25 pounds. I tend to be VERY weak in the biceps and shoulders and VERY strong in the triceps and back.
Hope this helps!
