Reading most of his short stories in order is a great experience. Yes, you hit some not so great stories, but from time to time you hit gold. Beyond Lies the Wub, Meddler and Paycheck are some of his early works that worth a read. Regarding Ubik, there is a Russian movie, Koma, that looks like it had Ubik as inspiration, and in that probably is more faithful than most Hollywood adaptations of his work.
