Bell Training
You will not be disappointed, the ground training covers all you need to know and then some. If you have 206 time then this is just a transition. (the 407 is a 206 on steroids) Flight training is fun, relax and enjoy it. Autos are a little different (at the bottom) but the rest is just getting used to the fadec system. The best thing to remember is if you have a fadec failure, fly the helicopter the only time you have to take immeadiate action is on an approach with low collective settings (Ng below 80%). The rest of the time the faults can be corrected without having to rush through procedures.
You should be able to download the AFM from the Bell web page. While in the site they also will have a list of discounted hotels for Bell students and transportation details.
Not sure were you are coming from but if its your first time then take the opportunity to enjoy the visit.
Best of luck
