play first few games with those simplified rules, so it doesn't get too complicated.
My advice is to just bite the bullet and play the regular game. The game comes with some tip sheets (simplified rules on one side, regular on the other) that should definitely use.
Download this latest FAQ. The one posted here at FFG is outdated.
Also, there are some great tip sheets at BGG. Those will definitely help.
When we added it to the collection, we just fired up the standard rules. In my first game, there were some fairly glaring mistakes, but the game was still a blast. In the second game, there were a few, but significant mistakes. In my third game, I think we got the rules down pretty well.
The thing about the simplified rules is that they can be just as confusing as the regular ones.
