EB 1.1 with Barbarian Invasion?

[jadam]

Greetings,
after having played EU:Rome and got that deep dissatisfaction you can hear about the official forums, I've decided to get back to RTW.
Now I'd like to play EB since it has got to 1.1 version now, and last time I played it, it well below 1.0.
I have RTW and BI expansion pack, my question is that does BI add anything to the game apart from the new campaign which I dont use anyway (Improved AI, possibilities, etc)?
Also if so, how should I use BI with EB 1.1?

Forgive me if it has been already answered, but for my search I could only find some info about 1.0 and even that I could not understand entirely.

Thanks

It's in the FAQ, and on the first page of the unofficial modding projects forum, here.
