Congrats on the new weapon! It's a reliable and verstatile bike, IMO, supported by plentiful aftermarket support to really tailor the bike to your riding needs.
There is no shortage of aftermarket support for those, i just picked up a plated drz400 dirt only model, its way too much fun! Enjoy your time and two wheels and some really cheap fill ups!
This is my 2003, she has a Clark tank, Renthal bars, Russel Day long seat (quite necessary imo over stock) and Ortileb dry bags. I've taken her on many a long adventure.
