Part of cycling is just paying your dues and toughening up your rear. You're going to have some soreness initially as you break in your butt. However, it should only be temporary.

As far as saddle sores, sometimes some people are just prone to them. You've got the right idea, but the body glide stuff doesn't sound like it's going to cut it. I'd try out some chamois cream, something like assos chamois cream, dznuts, or chamois butt'r. Apply liberally to both your shorts and posterior and your saddle sores should be gone. They'll reduce friction, inhibit bacteria, and prolong the life of your shorts as well.

Hope that helps.
