My car is in the collision center at the dealership I work at after hitting the back of a truck a couple of weeks ago. I love my car, but am selling it after it comes out of the shop, and buying another one...this time a black 2003.
My car was a 2003.5, but the black one that I am looking at is a 2003...but is beautiful!! I can live with the "doggie-door" trunk, the lack of trunk release, lack of tire monitors, and even the lack of a place to plug my cell phone...but I can't live with a difference in engine performance. Was there an upgrade power-wise from the '03 to the '03.5?

Nope. Just make sure all the tech service bulletins have been applied to your car. Some early ones had trouble with things like the A/C compressor, if I recall, etc. Those issues were resoved for the 03.5.
I don't think the engine power was boosted until 05.

As I stated above there's lots of differences between these cars. There's also many more differences between them and the 2004 model year cars.

03 vs. 03.5
I have one of the first 03.5 G35 sedan's that came out. Our car was delivered in October of 2002. First of all, the trunk was changed with the cut-out removed and smoothed over. Infiniti lettering was applied across the trunk. Secondly, there was a second power outlet added to the interior. I tried to order one with Twilight blue. Twilight blue was discontinued and then was brought back 6 months later as a color option. I ended up getting Black Obsidian instead. The auto transmission was the only one available. I would have gotten a 6 speed, but I was so excited to get a G35 that I got an auto instead. I have a catalog of the 03.5 model.
