Seriously, I recommend you track down some guys local to you, and get some help.
If nothing else, get a simulator, and fly it until you can take off and land on the sim. Some guys naturally pick up flying these things, but most don't. And the guys that do, already have knowledge of how a plane should fly. I don't mean to be discourging, but I suspect your first flight won't last long, and you won't have to worry much about how to land correctly.
At the very least, do a lot of reading about how planes fly. My personal favorate site is "See how it flys"

It's written for private pilots, not RC, but all the theory is the same, just ignore the bits about what to look for out the windows and guages.
As for how to take off, you'll want to take off in to the wind. For starters, wind less than 10mph is a good idea. The plane can handle much more, but only with an experienced pilot. At full throttle, that plane will probibly go close to 60mph.
Don't jam the throttle forward. If you do, the plane will pull to the side and not go where you expect. Instead, slowly advance the throttle in stages. Add some throttle, then use the rudder to correct the track. Then add more throttle, and correct with the rudder again to keep it going straight. Once the plane reaches flying speed, you'll see it kind of skipping on the wheels. It might even take off on it's own. That that point, you an feed in a very little amount of up elevator to raise the nose. If you do it too much or too soon, the plane will leap off the ground, and probibly stall, drop a wing, and likely cartwheel.
