I never took anything called "inorganic." I took intro chem (1 semester for those with considerable chem background, otherwise you needed intros 1 and 2), orgo I&II, and "equilibrium and analysis" (essentially acid/base stuff), all with labs. My guess is that had I done the two-term intro, I wouldn't have had to take E&A. I had no problems, even though my school offered a course called "inorganic" -- essentially an advanced course -- and with our respiratory block coming up first thing for me this fall as I begin MS-II, I think I'll have my bases covered really well! The take home message: take intro, two orgos, and something else, be it E&A, intro II, "inorganic," or anything else that may qualify. The best folks to ask would be the premed advisory folks at your school.
