A couple of things I noticed in your plan...
1. If you only have 10 hrs a week to train, I wouldn't run 70-80 mpw. Spend more time on your bike.
2. You need to get used to being aero for 5-6 hours. That's not going to happen on the spinning bike at the gym.
3. I know a handful of guys who are 2:30 marathoners who have not run 3:00 off the bike. It takes more than run fitness to run 3:00 off the bike.
4. Get swim instruction as soon as possible.
5. I'd search for posts by BrianPBN to look at different nutritional strategies for IM. He posts plans from pros and AGers he works with
