In general, the systems part of E170 training is very easy. If you have flown another regional aircraft (CRJ or whatever), then systems will be almost mind-numbingly easy. Of course you need to study, but I think you will find class ten times more boring than it is difficult. Indoc is Indoc, and the hardest part will be trying to not just rely on what you already know from your current job. Rest, Duty, 3585...so much of it is the same you might snooze and miss the differences. Sim training is not bad, and is like any other sim. Know your flows, and don't rush. Good luck, and once you are done training, we look forward to having one more guy with outside union experience to help us fight the fight.
