You are right, I was inconsistent.
I'm imagining a fair amount of archery in the game, but intending to be a capable Melee fighter. The shield spell is very useful for Melee, when you usually would not have cover.
I'll have to think about the Expertise/Trip route. I'm currently running a fighter with Trip and found it to be less than satisfying. It seems to me that you have to build the character specifically for this feat in order to take good advantage of it.
I'm not going to be taking a lot of Sorcerer levels. The character is mostly a Barbarian/Dragon Disciple and I want it to be a capable front line fighter. I'm seriously questioning if I would ever go beyond 4 levels of Sorcerer.
Once again, thanks people for the comments.
