oh, i didn't realize you had a thread up already.
For starters, whomever told you that anavar would do the trick is full of shit. There isn't a shortcut unfortunately, although there are tools available to help make things more efficient. Anavar is not one of those tools as it may exhibit fat loss properties, but those properties are greatly exaggerated.
The very first thing you need to look at is your diet. If your diet isn't up to snuff, neither will your results be. This is the single most important factor of any body recompositioning bar none. I strongly recommend you spend some time in the diet forum and soak up as much knowledge as possible. Having been in the military (thanks for your service!) likely means that you have the discipline to follow what you learn. If you can get that part nailed down, the rest will be a piece of cake.
If you want to have a professional take care of this for you, 3j (the resident nutritionist) is more than capable of attending to this task. I learned a great deal from him, and i know many others have as well. You can find him in the diet forum as well.
Are there any specific questions you have regarding exercise? It's quite a broad topic, so without any specific areas you feel you're lacking knowledge in, it's difficult to answer.
As far as putting on too much size; i hear this a ton from both females and males starting out. The simple truth is that you have to have three basic components to do this: Eat to become huge, have the proper hormone profile to become huge, and train to become huge. It cannot happen on accident, nor will it happen on a small course of anavar (when/if you're ready for that step). It can only be achieved by working at becoming that way deliberately.
hopefully that gets you started as it appears you have quite a journey ahead of you. The best piece of advice i can give is to be persistent and consistent. If you burn out, and take a day off - that's fine, just get back up again and hit it hard the next day. Don't fall into the trap of thinking that you have to wait for the stars to align perfectly before you can start up again - as they won't.
