If you Burn in 2013, you will have started younger than almost everyone here, so there's not going to be a whole lot of people shocked by your having been "locked down".
The best things you can do to get there are :
1) Read the Survival Guide (linked below)
2) Meet local Burners (anyone in your region, or even regions that are just kinda near . . . you might have to travel to rideshare)http://regionals.burningman.com/na_index.html
3) Save your money! You might have to go on your own.
Oh, and if you have relatives who gift, add camping stuff to your wishlists or ask for gift cards to helpful stores.
Best of luck. People are pretty nice here if you make an obvious effort to find an answer first. (If you don't, they will hand you your keister).
