Just want to say welcome to the forums!

First of all, since everyone gave you plenty of advice, i just want you to know that wen you do get it lucid (probably in a couple weeks) you may seem a little excited at first, but you have to be sure not to get very excited. You need to stay calm and become focused on the dream. You also want to pick a few reality checks, to see if you are dreaming. These comsist of plugging your nose and trying to breathe through it (if you can, you're dreaming!) looking at your hands (count the fingers and note their size. I almost didn't get lucid because, even though all my fingers were there, one was really short) and also looking at a clock, turning away, then looking back a few seconds later. If it changed (aside form one minute ) you're most likely dreaming!

As far as controlling your dreams, it usually takes a few lucids (about 3 or 4) to be able to do most of the things. It all comes with practice.

Good luck, don't give up, and have fun!
