Supposedly the buses begin running at 6:30am for ADRs. That might be a problem for your 7am one at CM. You might have to bite the bullet and take a cab for that one. If you get the cab by 6:30am you'll be fine, won't take more than 15 min to get there.
For Boma be at the bus stop no later than 7am and you should make it.
The comment about the scenic route was that if you don't know the way you should be heading the driver could take a longer route to run up the fare a few bucks. Get a map from bell services and have an idea of what way you think would be the shortest just to protect yourself. And no I am not suggesting that cab drivers would do such a thing.
