Given that just half of the width is available for reducing chain rub, that leaves roughly 0.35 mm narrower. That's a pretty small amount in anybody's book. A ten speed chain isn't going to do much to solve the problem. It sounds more like a chainline or derailer adjustment problem.
For 287: A lot of your problem could be solved by not using the combinations you are using. The gears are probably duplicated elsewhere in your gearing and you don't really gain anything by using the inner ring and those small cogs. Go to Harris Cyclery website and use the gear calculator. Then avoid those combinations.
I have to also disagree. Like it even matters what crankset goes with what 8,9,10 speed rear cluster. Pick the chain based on what the rear cluster is only. If the rear is an 8 speed, use an 8 speed chain. If the rear is a 9 speed, use a 9 speed chain. If the rear is a 10 speed, use a 10 speed chain. The chainring thickness of a 8,9,or 10 speed crankset is all the same.
