While Ichigo at first obtains both his Shinigami powers, and a zanpaktou by absorbing Rukia's powers, it is never made clear if that sword is in fact Zangetsu, or simply a side effect of the transfer of powers. Making it speculative as to whether or not this sword was Zangetsu.
What can be verified in both the manga and anime, is that the name Zangetsu is first used directly after Ichigo's trial in the shattered shaft. This is also the first time we see the materialization of Zangetsu in the form of a older man dressed in black.
While the difference in appearance can be explained by the difference between the swords normal state and it's shikai state. We have never seen Zangetsu's normal state since the name was first used.

As of 4/5/2010, there has not been a final battle between Ichigo and Ulquiorra in the animated series of Bleach -- at least, not in an episode released by Dattebayo. The last complete fight between the two (where one of them is defeated) is featured in episode 161 through 162. The next time they meet is in episode 216, then again in 226 before filler episodes begin. In the immediate future, it appears that Ichigo and Ulquiorra will meet once more in episode 266. In the manga, their final battle starts toward the end of chapter 339, "The Deathbringer Numbers," and finishes at the beginning of chapter 354, "Heart."
