As is true with most everything else, you can read the user's manual and make the technology physically work. However, it doesn't necessarily make you good at what you do. I agree with the training upfront to establish good practices. I would also recommend continuing to discuss methodology and findings either on this board, with carefully chosen "mentors" or both. I've seen my share of poor ODS and Modal projects (whether it was poor planning or a complete lack of understanding of diagnosing the available data) and it makes me ache. I took an ODS/Modal class with Tony back when he was still with CSI (75 years ago it seems) and I agree that he'll definately get you started in the right direction. Best of luck!
