Zuma, If your skewer bent because it was loose, its possible that is what took out your rotor. If the hub can move to a position other than perpendicular to your forks or chain/seat stays, all of the suden your rotor will be wedging against your caliper. If your hub is set up properly, the axle is bearing some of the load and the skewer is just clamping everything together keeping the dropouts sitting on the axle. Depending on your hub, there may be a solid axle kit available for it, but I don't think thats the issue... yet.
As far as technique, it varies from landing to landing, and unfortunately the answer isn't as simple as landing flat on both wheels at the same time. If you try that technique on an HT or a 20" you'll start busting things, and once you beef up the bike to handle and resist the forces being applied, your body will become the next weak link. When you're landing, force is being exerted as the bike crashes into earth. You have the weight of your bike and the weight of the rider being pulled down by gravity. The bike should be plenty strong to handle the stresses of it's own weight, but what you do with the weight of the rider is what's more important. There are two ways to deal with the forces involved; the first is to absorb them (a la full squish rig), the second is to divert them. Since you're on a HT, you can't rely on the bike to fully absorb all the energy of the landing. So your body has to help with a combination of diversion and absorbtion. Basically you'll still be rear wheel dropping first, but as contact is made, your body needs to absorb some of the energy (knees and arms), and you need to divert the remainder of the energy to forward motion. Your body works like the best shock money can buy. After you ride for a while, your brain knows how much resistance to apply (think of it as compression dampening) in order to let the body absorb the impact, yet still stay firm enough to control the bike and not wrap yourself around the top tube. Unfortunately, the best shocks in the world have their limits and at some point if the drops get big enough and the landings are flat, you're going to need to get a different rig. Dig around for videos of guys on 20" bikes and trials riders doing drops to flat. Watch the technique and just ride more and I bet you'll be doing better in no time. Oh and double check those QR skewers to make sure they're tight before the next ride
