Improved Shield Bash, and other shield questions

[Moto Jojo]

The Improved Shield Bash feat from Defenders of the Faith allows you to shield bash an opponent and affect him as if you'd bull-rushed him, except that they only move 5 feet, and you don't follow them. My question is, since being moved by a bull-rush normally provokes attacks of opportunity, does this mean that someone with the Improved Shield Bash feat gets an AoO against an opponent they successfully knock back?

My related questions are:
What are the normal modifiers for making a shield bash attack?
- using only the shield during a round
- shield bashing and then using a sword, or vice versa, in one round

We play it such that the basher doesnt get an AOO, however, if the 5' move moves the bashed through someone's threatened space, they get on on him.

That is the most logical way to do it IMHO.

I agree with the lone gunman about the AoO. That's also how we play it in our group.
As for your related questions. If you attacked with just the shield in the round I believe you would only get off hand weapon penalties which are -4 I think, unless of course you had Ambidexterity, then there would be no penalty at all.
If you attacked with the shield and another weapon you would get two weapon figting penalties as if you were using a light weapon in your off hand. I think under the shield description in the equitment chapter it says shields are always considered light. Also I think you can only bash with small and large shields, no bucklers or tower shields. I may be wrong on that though.

Agreed, since it "...affects your opponent as if you had performed a bull rush."
