Welcome. If you haven't read the Survival Guide a few times, go nuts! That'll show you a lot of ropes right there, and give you a beginner packing list. And of course, we have info for days here on ePlaya. Google a keyword + ePlaya if you don't find what you want via category or the Search tool.
There are lots of Texas Burners. Try this link, and check Facebook as well. A rudimentary search shows me there's a North Texas Facebook group, for example. http://regionals.burningman.com/
Incidentally--you won't need to put "willing to break the rules within reason" on a camp application. Camps/groups generally fall into 3 categories: 1) entirely sober, as a selling feature 2) a clearly-stated alcohol-but-no-drugs policy, or 3) whatever, but keep it to yourself--do all your jaywalking and disturbing the peace in your own tent, not in the shade structure where hardworking law enforcement officers are hoping to strike night-vision gold.
Camps will tell you if they're straight edge. If you ask how liberal they are, however, they may assume you're undercover.
